@V2Blast have you given any thought to taking the Alert feat at level 8? (I am not sure that the XP grind is helping us, as we have so few encounters and the sessions seem to get shorter ... and I have an idea that I am kicking around about milestone leveling. Will discuss with the group after the first foray into the sahuagin fort during the next session)
Anyway, Bron has decent dexterity, and Alert +5 to initiative and Feral Instinct at level 7 gives you advantage on Initiative rolls. And as you all go up the chances of having invisible or unseen attackers certainly won't decrease. 😁
