The Simple EHP calculator was an idea of mine after looking at many many other EHP calcs.
I found them cluttered when I just wanted to check to see if a new item was better than an old one!
That said, with any tool you lose a few things but that's OK! The good out-weighs the bad eh?
Now, how should I add this power into the calculator? It gives 20% of the damage into hp for 3 seconds. That means that you have an extra 3 seconds of life before you die?
I've not had this skill so someone will need to tell me if that's the way it works.
