Making it a drinking game might help to hold Terrik's attention.
We need to make that drinking game.
Take a drink whenever:
1) Someone needs a teleport pyramid passed to them.
2) Someone says "I don't have a rez scroll."
3) Necrofire literally fills the entire screen.
4) Terrik spends 3 or more consecutive turns CC'd, TWO drinks if the phrase "Glass Cannon" isn't mentioned by anyone because of it.
5) Snuffles' arrow is blocked by an obstruction that the game told him was not an obstruction.
6) Gas takes more than 15 seconds being indecisive about how to spend his last AP.
7) Dei groans in frustration.
8) Terrik falls asleep during combat.
9) "What are we doing here again?"
10) Terrik deals more than 1000 damage to an ally.
11) The game must be reloaded from a save, two drinks if it's for something that DIDN'T involve combat.
12) Dei uses Backlash and it doesn't put her in position to backstab.
13) Dei uses the Chicken/Rupture Tendons combo and her target then refuses to move.
14) Gas or Terrik accidentally CCs an ally.
15) Gas can't remember the word "Persuasion," two drinks if he calls it "Bartering."
16) Snuffles steals a kill.
17) Terrik kills an unharmed enemy in one turn, two drinks if Omega Flowey wasn't involved, THREE if he manages to not damage any allies.
18) Someone complains about how bad their gear is.
19) Someone makes a move in combat and immediately says "That's not what I said to do!"
20) It is revealed that the party has lost out on something noteworthy because they murderhobo'd a quest instead of doing it properly.
21) Snuffles uses "Pet Pal" to cause harm to an animal.
22) Snuffles gets a new bow within 20 minutes of having gotten his last new bow.
23) Dei demands an NPC be kept distracted so she can pickpocket it.
24) A successful persuasion roll still fails to prevent combat.
25) Somebody asks Dei to pickpocket a NPC she is unable to pickpocket because she already pickpocketed it earlier in the game.
26) Terrik dies in combat and it is decided to leave him dead until combat is over, to conserve rez scrolls.
27) Gas tries to clog a poison/oil vent with a barrel or crate. TWO drinks if he actually succeeds. THREE if he succeed when the oil or poison is already on fire.
28) Terrik's poison inadvertently heals an enemy.
29) Terrik gets all his source points stolen from him during the same combat encounter.
