Ritual Sacrifice GUI problem and other feedback

When using controller input, Rare Enemy corpses have convenient icons above them.
When approached, these icons change their looks to indicate that the player can use RS skill to target this corpse.

These icons do not exist while playing on kb+m and wsad input settings.
Simply hovering over the corpse while pressing RS skill button is also not enough to cast the ability on this corpse - if you don't stand close enough, your character will just use RS on themselves.

It would be great if we at least got the icons on mouse input, but it would be even better if we could just click them to have our character approach and cast the ability.

Another issue with the skill is the lack of information about active modifiers.
A simple icon we could hover over to see them listed (like we can do on the Tame Beast gem) would be enough, but specific buff icons would be amazing.

There really aren't enough Support Gems working with this skill.
We can use a lot of Support Gems to buff modifier abilities for Tame Beasts, why not here?

A suggestion about the RS skill:
Getting all modifiers from a rare monster is strong enough to warrant the short duration, but what about self-cast?

Perhaps we could only have one "Ritual Sacrifice" buff active, and it would be one of the two:
- a short duration buff from the rare corpse;
- a long duration (maybe even permanent?) single modifier buff from self-cast.

--

A suggestion about stolen modifiers in general:
Could we have monster modifiers effects on allies use different colours, and perhaps even sounds?
It gets really confusing, especially in party play with multiple Beasts.
You pioneered the tech with Blackflame Covenant and it would be a huge QoL improvement for many players.

Thanks and keep up the good work!
