Arcane Ward Questions

[Chaosvii7]

About to recommend Arcane Ward to my roll20 wizard's player. Had a question about the math behind it:

* Is it 2(Level + Int Mod) or 2(Level) + Int Mod?

* Is that a maximum? Does that mean that when he casts a spell to fill it up, does it add onto that if it's at max, or can it only be as high as the default value?

2(Level) + Int Mod

This one seems the most natural reading. And it seems that it sets a maximum which can be refilled as he goes.

to me the key word in the description is "regains", so the first time you cast a qualifying spell it is at that total then subsequent times you can regain lost hp on the ward.
