Advanced tooltip
I think there needs to be an advanced tooltip option. The most important reason for this is to show exactly what works on spells and what works on melee etc. For example hovering over Solael’s witchfire and its upgrade with advanced tooltip could show in glowing blue what affects spells, and glowing green what affects melee in addition to text describing the game mechanic more.
The most important information players need is what will work on spells, melee and such. This info should be available ingame and should not need googling, foruming, wiki etc. Other information should always be displayed here.
It is also very, very important for the game to explain better what skills rely on weapon damage if at all. This information is something I also consider to be mandatory.
As a fairly new player myself I see a lot of other people struggling with the same things. A lack of BASIC information. This is also needed for devotions as some devotions can be too vague.
