Yeah, that quest.

Taunt and some other skills such as earth absorbation shield, avatar of elements(useless imo considering that the adept skills provide the same elemental absorbation shield).

Also, If I recall, there were also some summon bloodswarm/bloodwasp skill in witchcraft? That was removed too. There are some leftovers from classic, for example, one of the accessories from winter king's treasure(its probably the winter ring?) gives you the art piercing ice shard IIRC, after you equip it, it gives you the normal ice shard skill. Piercing ice shard is now a summon-only skill(many other skills which were actually usable by the player are now summon-only skills).
