Spells: Max HP with Talisman

[Enderenter]

So, I was given Talisman of Altuna by a shaman today, and my max HP increased - but my health will not regen above what the previous max was. I even tried to Mend, which was successful, and didn't heal me at all.

The shaman who buffed me said they had that happen with some cleric buffs, where their HP max was increased - but their HP would not regen past what the max HP was prior to the buff.
