The Magician's Tower

"Grants you an innate resistance to charm spells."

Does anyone have an positive experience with this? I haven't bought it yet. I assume it was added for a reason. But I think on events like Krond, the charm is unresistable, so I doubt this AA does any good for raids like that one. Maybe it's only good for group stuff? Really hard to tell I guess, it's not something easy to quantify.

i think it worked for people in mindshear and that helped a lot

Only really useful for SoD events. As you said, Krond's charm mechanic is unresistable, as are most other raid charms. The AA does help protect against the Aneuk charming in Korafax, and some charm mechanics in the raid events (mindshear, aneuk trash etc).

It "helps" in the extent that it doesn't "hurt" you on SoD content that charms, but its closer to Packrat than Spell Casting Mastery level of useful.
