Both Lady Geist and Victor have incorrect, vague or inconsistent skill descriptions in regards to their self damage, making it impossible to discern how they should behave without reading the patch notes.
Lady Geist:

- The description doesn't reflect the changes from the recent big patch, which changed her damage from current health percentage to percentage of bomb damage. The current description is exactly the same as Malice, which still functions like it did before, taking a percentage of her current health. It should be changed to mention that it does 30% of bomb damage to her health, or even straight up just show a number with scaling, as there's no reason not to show that number since it only changes when spirit changes.
- The description does mention the self damage type is spirit, but the spirit damage icon is missing.

- The description is correct, as Malice actually does damage proportional to current health. But it is missing that notion - it's not clear if it does % of max or current health.
- The damage can be mitigated with spirit resist, just like with Bomb, but it's not mentioned here. Not saying it's mandatory, since I think it's clear from the icon - but it's inconsistent with Bomb.

- It incorrectly states it does spirit damage. It does pure damage, which can not be decreased by spirit resistance.

- It incorrectly states it does spirit damage to self. It does pure damage, which can not be decreased by spirit resistance.
In general, it seems that just using pure damage for Victor's self damage descriptions, while using spirit damage for Geist's self damage descriptions should be enough to clarify the intended behavior. Then there would be no need to explicitly state "Self damage type is x and can/not be mitigated.", as Victor would no longer confuse people with spirit damage that can not be mitigated.
