Earth Spike -> Heaven's Drive pre-requisites wrong for Warlocks (and classes below)

This is only a minor issue, but while Heaven's Drive description is accurate regarding the different pre-requisites for one to get it as either a Sage or a Wizard, the Skill Window "tells" Wizards and all classes related that you only need level 1 Earth Spike instead of level 3.

So, whenever I reset skills and mount a new skill tree with Quagmire, if I forget that detail, the whole job is fruitless as the skill tree is reset again, probably to avoid bugs that could give the player two extra points by bypassing the established pre-requisite.

I repeat, this is only a minor issue, but it might be worth your time.
