I have a question about the spellcasting DT roll. I may not be reading it correctly. It states 'The Difficulty Target (DT) for all spells is: 10 + Magic User Level + Magic User's BRAIN Bonus.' This seems to me that you are punished for being higher level. I see in other games where the DT would be 10+spell level and you would try to roll 2d10 + caster lvl + brain bonus to beat the DT and cast the spell. Am I misreading or not understanding something? I do like the game very much!
These spells come from the SRD 3.* system. All of Microlite20 is from that source. Unless the spell calls for a test of some sort they are automatically a success... you just have to pay the cost in HP. The difficulty test comes into play occasionally when you are casting against another magic user who can use a counter-spell against your spell, and monsters that have a natural defense against magic.
