It's actually not a huge issue for the campaign (plenty of other things), but one of my players has become a quite scary mind-messer (and another is not far behind):
A favorite tactic is Enslave the Mortal Mind, which he ran up to a Spell Mastery 6 (including quiet, still, fast, multi-cast and penetration), Penetration 6, and he's got 20+ in both Rego and Mentem. We've had 110+ sessions in the campaign... available for those who enjoy such things here.
Of course, this is quite effective (really op as RAW) against humans/faeries as well much older magi than himself. Especially when combined with Rego and Perdo Mentem effects to alter or remove the memories of said enslavement - often combined with a sleep. Not to mention he does have Shroud Magic too...
Since Mentem can be quite op, while being handled in the campaign (much better than Leap of Homecoming which I have started hating with a passion) it has led me thinking kind of ways it can be mitigated or challenged but still rewarded (as a rightful specialty) - and I would love some input too.
- Clamp down more on the eye-contact mechanics. After all, the mind must be perceived to be affected by magic, and the eyes are the window to the soul :).
- As the target is actually fully enslaved - they lose all creative thought processes. I.e. does not volunteer things at all and need very detailed instructions to really accomplish anything (good for roleplay). Since the spell is so heavy-handed otherwise, this has solved some of the OP issues so far.
- Since the spell is high level and duration:sun, it's perhaps not so easy even for the magus to remove/dispel it at will - which may require timing around dawn/dusk with the other Mentem effects. Leading to challenges or complications.
Any other thoughts on dealing with Enslave the Mortal Mind, as well as other high powered Mentem stuff? (I guess range: voice or sight variants could by RAW really mean problems)
