Thoughts on v0.2
I mostly picked 4 hours because it's a number I could easily remember (14400 seconds) and I usually don't play longer than that... or live longer than that.
I kept the shorter duration spells that can be cast on other people less to encourage cooperation in multiplayer, so you've still got to seek each other out for buffs.
I reduced the reuse time of barkskin and strength of stone so you don't have to wait to re-cast it when you die.
As always I welcome thoughts and opinions on these changes.
