DESIGN COMMENTARY

Before anyone gets funny with the word "Peg," please keep in mind its origins from "Pegboard" where the game is played.

You may recognize the game by its many other names such as "Plinko" or "Pachinko,"  but those are actually proper nouns. It's a little alarming how there isn't a widely accepted name for this game beside "pegboard ball game." I ended up creating my own ("Clinker") that is as similar to Plinko and "tinker" as possible.

I added a pinball ball launch into the sword's hilt. Fun!

The pegsword's boons were surprising to balance, too. For starters, because it requires attunement, it needed to have a base benefit (+1 weapon). The rest of the boons had to be on par with the opportunity cost for attunement (because a +1 weapon doesn't require attunement). Normally in a game of pegboard ball game, your best boons might be near the edges of the board because it's harder to achieve. However, this weapon uses the 2d6 damage roll to determine its boon (my idea to reduce the rolling delay), so I also had to take into account that rolling 12 damage is already pretty great on its own while rolling 2 damage is unfortunate.

Overall the chances of producing no additional effect (roll total of 6 or 8) is 27.8%. This is the "downside" of the gamble, which isn't that bad.
