On page 12 of the Dungeon Adventures Companion (Book 2), in table EA - ENCOUNTER A, in entry 76 SIREN the [K] entry reads: "Table I/W/TA+", there's no numerical value to the "TA+".

Thanks for the tip, I didn't check the tables ahead of time and wasn't aware of the Invisibility spell, that's certainly a game changer!

Yep, was out of fate (might have misspent it) and my adventurer is a sorcerer with 21 DEX, so he died trying to escape. I've trudged along and cleared a Pit of the Giant Rats, no dragons this time and stumbled on the Manipulate spell... can it really be used at any time, on any roll (except an already manipulated one)...

Maybe it's a bit early for this and I should give it more time and go through a couple of adventurers but I'm already thinking about some mitigating systems: 1) Have settlements provide an Encounter Modifier for encounters and quests spawned within their hex and adjacent hexes (not retroactive, if the quest was already there, it keeps it's old modifier). ex.: a city might give a -40 modifier in its hex and a -30 modifier in adjacent hexes, a town might give a -30 modifier in its hex and a -20 modifier in adjacent hexes, ... 2) Instead of having a single adventurer, having a stable of adventurers (maybe based on the highest Rep, so start with one adventurer and when you get to Rep 2, create another one). Only adventure with one at a time but when they meet up in a settlement have them exchange equipment and gold. Again, maybe I'm exaggerating and should just continue as is or maybe go on one of those campaign in the other books.

What about when generating WB side quests that adds HP to the final boss monster? Ex: The rolled boss is Goblinoids 3/3/2 with +10 HP, does it become 7/6/5?
