Holy crap, the ForgedAnvil Character Generator is amazing.
Put in an experience total. Put in your raw die rolls or the “standard array.” Then start choosing, using pre-populated drop-down boxes, all the things that can be chosen.
Weapons and armor? It’s in there.
Spells? Feats? Languages? Yep.Even handy look-ups for spells and feats.
Multi-class support? Yes.
Change your mind, and want to convert a Level 15 fighter from Champion to Battle Master? Might take you five minutes. Ten tops.
It also provides a detailed summary of everything your paper man can do, with game mechanics.
I will almost certainly be making my characters with this program for the foreseeable future.
