*In Response To Summoning The Elder Next to Haldor" - Yup, the shield gives you a field of invincibility. The attacks are re-directed in a strange angle. The point is, if you happen to be lucky enough, Haldor iia godsend.

All enemies ignore you when you enter the field. Only downside is if you are island-side and it walks into the sea, which you have to lure back onto land.
