First-time Player: Help with Understanding/Optimizing Build

[Mescalinic]

even if mindsight's not allowed, the mindbender dip's worth it for the telepathy alone.

would you say that Telepathy alone is strictly better than dipping in Shadow Adept?

also, Arcane Disciple seem too cool and versatile to ignore... but what's the usual/optimal strategy?
1) WISDOM 13/14 and "waste" an item slot to use Wisdom-enhancing equipment to cast all the spells of the chosen Domain, or
2) WISDOM 14/15, no enhancing items and just casting up to the level 4-5 spells from the chosen Domain?

I don't need to decide everything about the build right now, but I must choose the characteristics and I'm not sure how much WISDOM is needed...

Making a beguiler thread is probably more effective. you are more likely to attract someone interested in beguilers in a post with beguiler in the title. Min/max it.

sorry, I didn't see your answer. Thanks, definitely doing that then :)
