Pen Nib

Adds Pen Nib, a new White powerup, to Muck. The idea is Slay the Spire's common relic.

Every 10th attack on an enemy deals 2x damage. Each extra stack makes it 2 attacks sooner, down to every 4th.

• An attack is one melee swing (a swing while holding a Rock included) or one arrow that connects with a living mob. Every mob hit by that swing takes the multiplied damage. A bow that fires several arrows counts each arrow that connects.
• A miss does not count. Chopping a tree or a rock does not count. Knuts Hammer and other hits with weapon type -1 do not count, and they do not spend a charged attack.
• The counter stays through the night and through death. It resets when you leave the match.
• The multiplied damage is part of the hit. Boss damage caps still apply. Ukulele, Sticky Bomb, AtG Missile, and Tri-Tip Dagger scale from that multiplied hit.
• With Crowbar installed, Pen Nib doubles the hit first and Crowbar then multiplies that result. A Survivors Bandit's backstab doubles the hit between the two. At the default 2x, doubling an integer is exact and Crowbar's rounding is the only rounding. A multiplier that is not a whole number rounds twice, half away from zero here and then half to even in Crowbar.
• If your client still shows a mob as alive after the host has killed it, that hit can spend the charge. The host drops the damage, so the charged attack is wasted.
• The stacking rule is this mod's own. Slay the Spire does not stack Pen Nib.
• Drops from White chests and shrines like any other White powerup. The pickup uses another White item's model.

Everyone in the lobby needs this mod, and the same other powerup mods. Gameplay settings are not synced. Use the same values on every machine. The launch log prints the numbers this machine is using, and the full powerup id table.

Changelog

0.1.3

• The drop is an original pen nib instead of a borrowed White powerup.

0.1.2

• The counter moved down to sit just under the Survivors ability list on the right edge, at 70% of the screen height. In 0.1.1 it drew on top of that list's first rows at every resolution. It still clears Muck's task panel and HP bars.
• The counter hides while the map, the inventory, a crafting station, the pause menu or chat is open, and while you are dead, the same screens the Survivors HUD hides under.

0.1.1

• The attack counter is readable at any resolution. It is bold white text on a dark plate with a drop shadow, 20 px at 1080p and scaled with screen height (27 px at 1440p, 40 px at 4K). It moved from the bottom-left corner to the right edge, below the crosshair, away from Muck's bars, hotbar and pickup feed. Not yet checked in game.
• The page now says a Rock counts as a melee swing, that each arrow from a multi-arrow bow counts, and that a Bandit's backstab doubles the hit between Pen Nib and Crowbar.

0.1.0

• First release. Pen Nib is a White powerup. Every 10th attack on an enemy deals double damage, and extra stacks shorten that interval down to every 4th.
