Thanks all for great advice. I think the build will be kinda cool actually. I'll go ASI +2 WIS twice and a Spell Sniper, with no druid in the mix, cleric(4) and fighter (8) only. Bless should compensate for leaving strength at 17. Bless is actually a perfect cast for a fighter I think, because CON proficiency helps and bless itself gives +1d4 on STs. Keeping concentration won't be that painful and attacking chance should be fine for both thorn whip and attacks.
