I know constitution lists an adjustment to Radiation/Poison saves (but does this apply to all "Poison or Death" saves, or just those having specifically to do with Poison?) but do any other abilities affect any other saves?
Initially, players at my table assumed the character sheet was drawing an obvious correlation that Energy attacks have something to do with STR, and poison/death saves have somethign to do with CON, etc. because of the way the character sheet is laid out. I dissuaded them from that notion by drawing the more obvious one as an example... INT shouldn't apply to Radiation saves since CON specifically details it.
Anyway - the dark lines on the character sheet connecting the abilities directly to the saves, although attractive, are perhaps unintentionally confusing.
