Late Blight

#Overview

Late Blight is the fourth boss in the boss order and the 6:00 boss on the wave schedule, between The Masher at 4:00 and Sir Strawman at 7:00. It is not part of the overtime cycle after 20:00, but a Boss Lair can wake it.

It has 2000 base HP, which is 1300 HP on Normal (boss HP ×0.65, see Modes), plus curse. Contact damage is 16 before time scaling. At speed 26 it is the third-slowest boss, after Ketchup Kraken (22) and Compost Titan (24), and well under Tibo's base speed of 62. Most of the danger comes from the ground it leaves behind.

It drops a chest, an XP gem worth 80 XP and a 25-gold coin (both multiplied by the biome's XP and gold multipliers).

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 6:00 on all four difficulties, with 1000 HP on Easy, 1300 on Normal, 1400 on Hard and 2090 on Nightmare. The Nightmare figure is 10% above base HP × the difficulty multiplier because Nightmare starts every run with one curse, and boss HP is multiplied by 1 + curse.^[1][2] Seeds s1 to s4 gave the same Normal times and HP.

#Fight

Late Blight drifts towards Tibo, fires slow spirals, and every 4 s of walking stops to drop spore pools. A full cycle takes 5.2 s.

#Spore pools

Five clover-shaped pools of radius 26 are marked at once: one centred on Tibo and four at random spots 20–90 units from him. After 1.2 s each pool strikes for half of Late Blight's contact damage. It then stays on the ground for 5 s, hurting Tibo for 9 damage per second before scaling, in ticks every 0.5 s.^[3][4]

Pools last 5 s and a new set strikes every 5.2 s, so the old set fades only just before the new one lands.

Pool damage counts as ground-hazard damage. It ignores the dash's protection and cannot be dodged, though armor still reduces it.^[5] The strike itself is an ordinary hit that a dash or dodge can avoid.

#Blight spiral

Every 3.5 s of walking, after a 0.9 s warning, Late Blight fires a three-armed spiral: 10 bursts, 0.2 s apart, with each burst rotated further so the arms turn at 1.6 radians (about 92°) per second. The bullets are large (radius 3.5) but slow (speed 45) and deal 7 damage each before scaling.^[6] Bullet count grows with run time (see Enemy bullets). At its 6:00 arrival the count multiplier rounds up to four arms, with bursts about 0.17 s apart and a new spiral every 3 s of walking.

Measured (headless tools/play.mjs, build main-B2gf34bA, seed wiki, standard mode, --god, Normal; the clock warped to just before 6:00; every other boss and every pest removed each tick, so the sim's hostile-shot counter only counts this boss): spirals of 10 four-bullet bursts about 0.17 s apart, starting 2.60 s, 6.77 s and 10.93 s after it spawned.

#On Nightmare

Nightmare replaces the five random pools with a fixed "crop circle" around Tibo's position: a central pool of radius 30.5 and six pools of radius 18.1 evenly spaced on a ring 79.8 units out, at a random rotation. All of them strike together after 1.2 s and become 5 s pools, as above.

The Nightmare spiral bullets also curve sideways as they leave, turning by about 48° in total over their first 1.4 s, with the curve fading as they go.

#Tips

• Leave the centre pool at once. It is always on Tibo, so moving about 32 units (its radius plus his own size) during the 1.2 s warning avoids the strike. Look at where the other four landed before choosing a direction.
• Don't dash through standing pools. The dash only protects against hits, not the ticking pool damage, and neither does dodge from Thick Skin or Ghost Skin. Walk around them.
• Fight it in open ground. Pools cover the area for nearly the whole cycle, so a long walk into fresh ground every few seconds is easier than staying in one spot.
• The spiral rewards distance. The bullets are slow, and the gap between arms widens as they travel. From further away there is more time to pick a lane between two arms.
• On Nightmare, stand in the gap between the centre and the outer pools. Counting Tibo's size, the ring from about 37 to 55 units out is clear of the central pool and the six outer ones. The outer pools also leave gaps of roughly 30 units between them.
• Bring burst damage. At 1300 HP on Normal it dies quickly to boss-damage bonuses such as Bacon Bits or Boss Buster. A faster kill means fewer pool cycles to deal with.

#Main attack

#Nightmare ground attack

Verified: Nightmare adds the cropCircle ground layout; other difficulties keep the ordinary attack. Its anchor captures Tibo's position when placed, rather than following him. A central pool of radius 21 and six satellite pools of radius 12.5 on an orbit of 55 strike together, leaving damaging ground behind. 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

#Nightmare bullet patterns

Verified: on Nightmare these replace the ordinary patterns above; they use the same pattern interval. Other levels use the ordinary list.^[10]

#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.
