...the barrier blocks any attempt to possess the warded creature (by a magic jar attack, for example) or to exercise mental control over the creature (including enchantment (charm) effects and enchantment (compulsion) effects that grant the caster ongoing control over the subject, such as dominate person).
crit check (1d20+3=4), based on the 23 AC listed that's three hits (1d6+4=6, 1d6+4=9, 1d6+4=10) with the axe and one hit (1d8+5=7) with the flail plus two weapon rend damage (1d6+4=7) so a total of 39 damage, man that's pretty weak round for Bertrand. Of course there is also a natural one in there.
