Hailey Colossus——From Excutioner to Molten Fortress

Glacial Syncytium and Nimber Fingers is optional, actually HP mods is also optional, and if u don't have enough capacity, then use a 0 level Spear and Shield. Only the first 7 mods are crucial to damage. Let's begin with those mods first.

Battle Mods

There's been arguring about Maximize Skill and Chill Specialist. Well, of course maximize skill has higher stat, but u already have Slayer sets and spear&shield, totally 34.2%AP, u may find maximize skill has higher single round damage but here's the key point——Dangerous Ambush. If u tried well builded hailey u should know that hailey can bring down all solo-able colossus within 2 rounds, that includes swamp walker, u need to hook to a hovering platform on the left and shoot its side armor. So most of your fire has been effected by the Ambush mod, which gives u 49.8% AP, and that's a lot.

And we both know, well, if u don't know, let me tell u, three types of Ability Power bonuses are multiplicative, u can gain Ability Power bonus from slayer sets, spear&shield ambush and battle mods like master series or maximize skill in this condition. And element AP can be obtained through battle element mods and syncytium mod, and also intergration mods. Ability type AP like Singular AP can only be obtained through reactors. So, when Ambush is activated, u already have 74% AP bonus, it's obvious u will need more element AP to maximize the damage.

I guess u already know which to choose now. Let's go to next stage then.

Critical Mutiplier Mods

Actually that means 'Stike' mods, and I hate this kind of naming. Hailey has a 5% base critical chance and Cold Fury will grant 40% base critical chance at max stacks, so typically hailey's base CC is 45%, and yes, without 27.7% CC from Front Lines, hailey can still reach 100% CC, actually without 64.6% CC from Emergency Measures can also reach 100% CC.

But we are here to discuss the former one, cause we have new integration mods which grants element AP and CM. Some builds are using Maximize Skill and Chill Intergration, which seems reasonable cause CI could make up some lost Element AP. We already discussed Maximize Skill, let's have a look at Chill Intergration.

First and for most, it's a strike mod, a CM mod, which means replacing Front Lines u will lose 64.6% CM, and our Intergration? only grants 10% CM and 28.7% Chill AP, so, here's the exchange, 28.7% Chill Power for 54.6% CM, will it be a good trade?

If u are using Chill Specialist, then this trade is apparently not worthy cause u already have 81.2% chill AP. For maximize skill, well it does have higher damage then Front Lines, but only about 9% higher. And most importantly this kind of combination still can't overcome Front Lines&Chill Specialist. Utimately I believe it's the poor stat of intergration mods doing, if it has more CM bonus or it's a CC mod, then it might be the best option.

Other Damage Mods

Quick answer? Not necessary. Even the syncytium. Before the reactor adjustments, I'm using a reactor without Colossus damage and I can still easily take out solo-able colossus, team up colossus as well. Hailey's damage is just insane, if u find it not so easy, u may need my Piercing Light build(https://tfdtools.com/builds/weapons/2821/hailey-piercing-light) as well, and remember to shot the weak points.

Power Modifier bonus is too little compared to Zenith's base 3627.4% modifier. Under just as I said, hailey's damage is already overwhelming.

Focus Fire? Don't put it! You have to remember that in Zenith's total damage, ability damage is the big one, decrease it to increase weapon damage is lossy. You may find your damage is even slightly lower after puting this mod. Then why put it?

All in all u don't need more damage mods, u just need 4 crits, ambush, slayer sets and chill mod, a builded Piercing Light like my build, and a proper reactor, then u will find out how easy colossus hunt can become.

So I suggest put a HP mod, and upgrade spear&shield to increase some DEF. And furthermore, I suggest u farm a slayer proccesor with toxin resistance. With all that above, u will find that Swamp Walker, especially Obstructer's toxin pool won't vaporize u anymore, u can even showering in it and finish all your rounds.

End

Okay sry for my long-winded, and thankes for u to read all of this. Acutally u can have 2 CD mods for the last 2 mods like nimble fingers and MP conversion, as I said, damage is pretty enough for solo colossus and more CD may provide u more versataility in the latter colossus and even in other modes like 400% infiltration to quickly vaporizes bosses.

Reactor Sub stats: Colossus top priority. Second stat: Critical Mutiplier>Singular Power>Chill Power.

Slayer Sets Sub stats:

Auxiliary Power: No strictly requirement, but a HP and MP recover out-of-combat would be best.

Sensor: Max MP&MP recover in combat.

Memory: DEF, another one, shield recover in combat? it's not strictly required.

Processor: Item aquisition distance, and a toxin resistance may prove helpful as I said before.

Colossus Tips

Excutioner: shoot the chest core, the rhombic one, it's possible to 1-shoot-down, if it isn't, don't worry, u will destroy the shell, and there will be a hit animation and u can seize that window to fire second shot and it's guranteed bring down. If u are not so confident with your aiming, then u can choose to shoot shoulder armors instead.When brought down, shoot the shoulder armor.

Dead Bride: Also suggest the chest core, and also seize the window after first shot, or bride get mobile it might be hard to aim. When brought down, shoot the shoulder armor.

Devourer: Chest core or shoulder, whatever, devourer has too little HP and as long as u successfully hit weak point, 2 fires will bring it down, and the third fire in most situations will finish it.

Pyromaniac: Shoulder this time, but still, if u get bad luck and both your weapon damage and ability damage didn't crit, it may go rampage. Storm Snare's damage is not enough to instant kill it now, but u can bring it down first and then charge one Storm Snare to finish it.

Swamp Walker: Hook to a hovering platform just on the left of the boss spawn location, run faster to ensure u make yourself ready on that platform. Bring Zenith out at the edge of the platform, and shoot its "shoulder armor", if u crit then 2 shots is guranteed bring down. And just finish shooting that spot.

Obstructer: If it's facing u directly, then start with chest core and then if it's moving and u find it hard to aim u can switch to shoulder.If someone draws its attention and it turns, then shot its shoulder or the sensor near its neck. If there's only one DPS dealer in your team, which is your hailer, u can use that 2 CD mod build I said and start with a Storm Snare, then empty your clip, and Storm Snare should be ready or almost ready by now, finish it with another storm snare.

Frost Walker: I always use Lepic instead so I don't have much experience about this one. But try to shoot the chest core, its weak point type march the Piercing Light.

Molten Fortress: If there's only one hailey in your team, then u'd better pray your teammates know how to tackle its rampage. This one got a huge weak point distribution, u can try anyone u want, it's really hard to miss.

Gluttony&Death Stalker: Zenith build not recommended due to their extreme ability crit resistance, u can use Cold Fury to enhance your weapon and using Legacy dealing damage instead. That will be another build to talk about.

Final tip, about Cryo Round, still the same, u don't need it, hailey's damage is already enough. But if your build and other equipments aren't so completed, u can use it as well. On cast is enough for the whole clip.

Thank you for reading my long-winded again!
