VonRichthofen said:Note that while you may actually learn these spells as a warmage or beguiler (or dread necro), you still can only cast them ONCE per day each.
So it is still fairly limited, apart from the Wis requirement.
Yep. The main advantage is to be able to expand capability.
A Beguiler with Slime actually has something to cast if Undead attack and can therefore contribute. A Warmage with Travel has a limited options to move around the battlefield.
But the weak DCs make are an issue and, coupled with the once per day limit, make this an enhancement and not a focus.
