It increases the damage of the explosion which is the main part of the damage anyway but the projectile itself is not affected

Roars do not stack, only the strongest takes effect

And roar and eclipse do stack together, they both are separate multipliers

Kullervo looks solid on paper

His 1st skill mentions being a heavy attack, wonder if it will be a pseudo exalted that is affected by heavy attack mods

Only valkyr's claws and excal's blade i guess and that's just because you cant abuse the gladiator mods like on Baruuk and cant use combo mods

You need at least 54.55% to get max with one infusion but idk if they can generate like that, also only the higher % of the 2 combined weapons matters so the 1st part of your comment is irrelevant

Same as the weapon you put the incarnon on but keep on mind they might change that in the future but more likely the dispo will drop significantly

Slash procs dont cut enemies, only raw slash dmg

Replace elemental mods and reflex coil with gladiator might, corrupt charge and either a bane mod or power throw, also sacrificial mods should be better, make sure you detonate the glaive mid flight with the heavy attack button

Glaive is probably THE strongest melee in the game right now, it one shots most steel Path enemies with ease

Most frames are weak to toxin tbh, with ash the best strat is to just stay invis and not get hit, toxin clouds and Moa tar are easy to dodge if you pay attention to your surroundings and invis is probably the best counter to toxin eximuses

There's no point on "cheap builds", if you dont want to invest into a weapon and its not a recipe for anything just throw it away after lvling to 30 and look for sth you'll want, at mr 16 you should have access to everything

You are missing out on a big damage buff from multishot, just spec out of the evolution if you feel like you spend the ammo too fast

Yes they dont count but DE said they might change that in the next update, so farm the lanthorns or wait till the update drops sometime in june
