Ziggurat 2

Shell us the special ability of Glyndor, the hero unlocked for beating the 3rd chapter of the campaign.

Glyndors gimic is he constantly loses mana from all sources but his wand at a slow rate. His special ability grants him 6 seconds of invulnerability, receiving mana for his three pools of spell, staff and alchemy for any damage he would receive.

I had to do this when his mana pools were completely empty as it didn't work filling them from half way, and thus managed it during my second fight. I can't confirm if this is required or if I maybe failed to get them up completely, but I wouldn't chance it if I had to do it again.
Any highly damaging enemy, or any group of enemies, makes this trivial even on the easiest difficulties. I was playing on novice and a group of goblins did this for me.

Happy hunting (>*_*)>
