Grater Golem

#Overview

Grater Golem is the tenth boss. It arrives at 16:00 on the wave schedule, with a Ring of Hay Bales. It is the first boss after the ×3 boss HP step at minute 16, so its 7400 base HP becomes 22,200. That is about 14,430 on Normal (boss HP ×0.65, see Modes) and 21,090 on Nightmare before curse. Nightmare starts every run with one curse, which adds 10% to boss HP, so there it actually has about 23,199.^[1][2] Its contact damage of 40 is the second highest of any boss, after The Harvester. It walks at speed 34.

It is part of the post-20:00 rotation, so a long run meets it again at 24:00, 31:00 and every 7 minutes after that (After 20:00). A Boss Lair can also wake it. It drops an XP gem worth 170, a 25-gold coin and a chest (Chests). It has no Nightmare variants.

Measured (headless tools/play.mjs, build main-B2gf34bA, seed wiki, standard mode, --god; the clock warped to 2 s before each minute and stepped across it; level-up offers taken first-in-order except Rotten Spud, so curse stays at the difficulty's start value): it spawned at exactly 16:00 on all four difficulties, with 11,100 HP on Easy, 14,430 on Normal, 15,540 on Hard and 23,199 on Nightmare. Seeds s1 to s4 gave the same Normal times and HP.

#Fight

The Golem walks towards Tibo and fires weaving rings. Every 3 s it stops and charges along a marked line. One charge cycle is 4.9 s: 3 s of walking, 1 s of warning and a 0.9 s dash. The ring timer is paused during the warning and the dash.^[3]

#Charge

When the charge starts, a line 26 units wide is drawn from the Golem in Tibo's direction. It is 288 units long, the distance of the dash (speed 320 for 0.9 s).^[4] The Golem stands still for 1 s, then dashes along the line. The direction is fixed when the line appears and does not follow Tibo.

The line itself deals no damage; the Golem's body does. During the dash its contact damage is multiplied by 1.5, so 60 at base before time scaling.^[5] Its body is wider than the line (radius 16 against a half-width of 13), so with Tibo's own size the danger reaches about 21 units from the centre of the line.

#Weaving ring

Every 3 s at base, the Golem fires one ring of 14 shots at speed 90, 14 damage each, after a 0.8 s warning. Each shot sways from side to side as it flies, about 10 units either way, 1.2 times a second. Neighbouring shots sway in opposite directions, so the gaps between them keep opening and closing.^[6]

Enemy bullets scale with time (Enemy scaling). At 16:00 each ring has 23 shots (14 × 1.64, rounded), they fly at about 112, and a ring comes about every 2 s.

Measured (headless tools/play.mjs, build main-B2gf34bA, seed wiki, standard mode, --god, Normal; the clock warped to just before 16:00; every other boss and every pest removed each tick, so the sim's hostile-shot counter only counts this boss): 23-shot rings 2.25 s, 6.18 s, 10.12 s and 12.15 s after it spawned. Easy and Nightmare also gave 23-shot rings.

#Tips

• Dodge the charge sideways. Getting more than about 21 units off the line takes Tibo about a third of a second, and he has a full second. Running straight away along the line does not work, because the Golem is five times faster than Tibo while dashing.
• Past the far end of the line (288 units) Tibo is safe from the dash. After a charge the Golem has to walk back, which gives Tibo time to attack or collect pickups.
• With 23 swaying shots, the ring's gaps are tight and keep changing near the Golem. A dash through the ring (see Dash details) is more reliable than threading a gap.
• Its HP after the ×3 step makes this the first real damage check of a run. Bacon Bits and Boss Buster raise damage against bosses, and Strategy suggests having a strong single-target source by minute 15.
• Compost Titan arrives at 17:00, so a slow Golem kill means fighting both at once.

#Main attack

#Nightmare ground attack

Verified: Nightmare adds the triangle ground layout; other difficulties keep the ordinary attack. Its anchor captures Tibo's position when placed, rather than following him. Three triangles leave a central gap. Each has radius 26, with its centre 35 from the anchor. They strike together for 25% of contact damage before mitigation; the charge still happens. Distances above are raw values: multiply them by Nightmare's areaScale of 1.45, but not counts, angles, ratios or times. This does not enlarge every enemy attack.^[7][8][9]

#Bullet patterns

#HP scaling

Boss HP is multiplied by a step factor depending on the run time (bosses.hpSteps), and by the difficulty's boss HP multiplier (see Modes).

The Normal column includes Normal's boss HP ×0.65, without curse. Other time scaling may also apply; see Enemy scaling.
