I have a couple of questions about Grasping Tentacle in The Watcher in the Water scenario.
GT has the forced effect:
" When Grasping Tentacle is attacked, discard the top card of the encounter deck. If that card has a shadow effect or is a Tentacle enemy, attach this card to an attacking character as a Tentacle attachment with the text: "Attached character's attack and defence are reduced to 0."
1. When exactly does this effect resolve? Is it the moment that the player declares attackers i.e. Before calculating or assigning damage to the Tentacle?
2. I assume that it is possible to avoid the forced effect by simply not attacking the Tentacle?
