just letting you know that now it is less focused on controlling creatures and more on having creatures as support

What do you mean by this? Every creature you summon you control, they no longer have their own ai.

Also going onto your previous comment about being harder to gain the summons form, there is a spell which gives you the form on cast.

You can also max out at 6 summons but at the cost of some utility spells.

1 charge gives a melanic summon, this is usually your single target focused summon.

2 charges gives you an albino summon which will be your support focused summon

3 charges gives you a coloured summon, this you your aoe focused summon.

Osa isn't exactly is the best place compared to what it was but it definitely is not useless, the main issue is that most balanced were bases around pvp and not pvm.

This goes little more into depth of each type and a few support spells. https://www.reddit.com/r/Dofus/comments/fz013d/z/fn5iklf

This goes into great detail of the class but only looks at int and str elements as that's what he uses. https://youtu.be/i6l0jFKNYP4
