This thread aged well.

It is hard to find any proper information about it in ENDWALKER and it is taken as default.

Nowadays Doton duration is reduced and even all ticks included it is never stronger than Raiton. Raiton simply outscales Doton.

There is however situational use of Doton if boss summons adds. However it is not single target anymore.

Doton low duration makes it very weak in single target. Still usable in multi, but not really that necessary either, skill lasting barely 16 seconds.

Highly suggest to use it only to place only in AoE situations with 3+ mobs, for 1-2 still single target rotation is just enough. Most of mobs are made to not even survive those 16 seconds of Doton duration, hence usage is without sense.

Unless you can get that juicy free Doton and reset mudras with Hide.
