Hm. Maybe it's just me, but I feel like knowing the light source statistics of daylight would be a lot more useful than prismatic wall. I mean, let's be honest. If there's a prismatic wall in the encounter, someone is already looking up the spell in the PHB.
Also not a super fan of all the optional rules being on it (hero points, climb on a creature, disarm, tumble, lingering injuries, etc.). I understand you must use them yourself, but I'd rather they were on their own sheet instead of placed on sheets with default rules.
Otherwise this is very nice!
