Yah we have no healer. In 3.5 a healer is still necessary unfortunately, unless we were just playing a pure roleplaying campaign which none of us is really designed for.
I plan adventures to work with the group's dynamic. And since Platinus has Crusader's Strike and Martial Spirit stance, he can provide some healing in-combat, as they can target allies within 10 feet. Jasper can also heal if you guys buy a Wand of Cure Light Wounds.
(The healer slot honestly is not a requirement in any game. In fact, it can be fun and challenging without one, but a wand of CLW works just fine anyway.)
Who had an extra 750gp?? i will take CLw at lvl 1 spells so no worries
