Deimos: Arcana: Hotfix 29.5.3 in PC Update Notes Posted November 23, 2020 So turns out Ash 4 didnt just get buffed at all, i mean yes sure his 4 got a nice change. But the cost for it is basically what makes him one of the funniest stealth frames to play: His Invisibility Let me explain it a lil bit. The most common approach for Ash with stealth is actually using the Arcane (Arcane Trickery: has 15% chance to proc on finishers and grants invisibility for 45secs[p.s. i also used it in combination with Arcane Ultimatum, which also procced on Finishers and grants bonus armor]), simply because the arcane is over 1.75x longer in duration than the Ash smoke screen ability (his 2) on 300% duration skill with its 24seconds. And even if one would go full duration, it would cost the strength wished for properly clearing rooms etc. So the question remain, why would the arcanes not work on the 4th ability Blade Storm anymore, even if you teleport with your 3 into the enemy masses and join the stabbing and slaughtering, it wont give a proc to either ultimatum (ultimatum has 100% on max lvl) or trickery (15% chance to proc). Some people would now try to argue its an exalted weapon and thus should not be directly benefitting from arcanes or smth. Its not an exalted weapon, because of several reasons. 1. Exalted weapons provide an extra mod section for this particular weapon itself, (e.g. Valkyr 4 exalted Talons, or Excaliburs 4 exalted Blade) 2. Ash 4 Bladestorm resembles more the shadow summoning of Nekros, and this ability isnt considered as exalted either. 3 Ash 4 Bladestorm isnt a weapon to begin with, since he creates shadow clones of himself. So ye, would be nice to get some proper statement, on why the change hasnt been called out when the Frame tweaks that came with Deimos Arcana were announced and why this ability would be considered as exalted weapon type.
