Telekinetic or Resilient Con
Diviner Wizard just hitting Level 4. I'm in a 2man party with a Life Cleric1/ShepherdDruid3 playing Icewind Dale. My plan was to pick up Resilient Con for Concentration Saves. But I haven't had to roll a con save yet, mostly due to my controlling foes with Web (and the druid's Bane+Mind Sliver).
Also the Druid is getting Spike Growth, which would do well with Telekinetic.
Should I instead take Telekinetic first?
Either way, I'm getting both feats, the question is which one at level 4, and which one at level 8?
For info, I have 18 INT and a +3 CON save already (rolled great). So I can either get CON save proficiency or Telekinetic (+1 INT).
What's my best level 4 feat choice? I'm looking for absolute optimized. This seems to be a low magic campaign, at least at these low levels.
