Shelltron and critical attacks.

[ArianeEwah]

Errrr Nope, they don't crit, atleast not unless its a specific mechanic. I'm 99.9% sure on that, but feel free to provide a source saying otherwise.

Unending Coil of Bahamut - during 5.1 - Nael deus Darnus' AAs on tanks

Bahamuts AAs also critted here, Twintanias AAs didn't, but through own exp I know it can. Just as all bosses in UWU can, and I am 100% sure all pre-ShB dungeon- and raid-bosses can, too.

Truth be told, I am yet to find any ShB source with auto crits. SE may have decided to remove auto crits from (raid) bosses because they removed Awareness as a CD. Strangely enough, at least trash mobs in ShB dungeons still have a chance to crit. Not sure about dungeon bosses.

Nevertheless, even if this just affects trash mobs and/or pre-ShB bosses, it's a QoL change that wouldn't hurt anyone. And it would make Sheltron more reliable.
