12 solo waves with modifiers you pick and Sol Heredit at the end. Every wave: kill the Fremennik, solve the south spawns, reinforcements at 40 s and off-tick the pillar stack. Sol is pure slash melee with AoE, a combo and a grapple.

Left icon: what hits you. Right icon: what to pray.

⚠→🔄

Wave start

Wait on the start tile: Protect from Magic on waves 1, 4, 7, 8 and 11; Missiles on the rest. On the 5th tick after picking a modifier run to tile A or B of the NW pillar while checking the south spawns.

→🚫

Fremennik warband

3 frems rush you and only attack in melee range, melee then magic then ranged every 6 ticks. Kill them now: berserker, seer, archer (SGS special on the archer heals). Do not walk away from them: you lose ticks.

⚠→🔄

South spawns and reinforcements

One south spawn: drag it to tile A/B and kill it behind the pillar. Two: off-tick them (rotate north or the A/B method). At 40 s reinforcements arrive: safespot jaguar/minotaur hugging the west of the pillar and off-tick the shaman. Return to the start tile.

⚠→🔄

Manticore and colossi

Manticore: charges 10 ticks then fires magic-ranged or ranged-magic then melee, 1 tick apart: pray before each orb launches. Javelin colossus (48): every 4 attacks a sky javelin lands in 6 ticks, move. Shockwave colossus: 56 magic from 15 tiles.

→

Jaguar and minotaur

Jaguar (waves 1-6): 3 hits of 47. Minotaur (7-11): 74, moves instantly and heals others within 6 tiles. Both safespot on the west side of the NW pillar (not with Red Flag).

⚠→🚫

Sol: area attacks

45 typeless AoE: no Protect from Melee (it does not reduce it and ruins the combo). Spear 1: 1 tile back. Spear 2: 1 tile back diagonally. Shield 1: 1 tile out of melee. Shield 2: 2 tiles. After every transition he always opens with a spear.

→

Sol: combo and grapple

Triple attack: turn on Protect from Melee on the exact tick of each hit (3 ticks apart; the 3rd takes 4 from 50%); early activation turns it off. Grapple: defend the slot he shouts (BODY, BACK, HANDS, LEGS, FEET) within 3 ticks; the last tick is a perfect parry.

⚠→🚫

Sol: beams and sand

Each phase (90/75/50/25%) adds a light beam (70+, 3 ticks to move; 2 in enrage) and 6 molten sands (6-8 per tick). At 10% enrage: sand every 3 ticks and beams every 7 s: dump claws and finish fast.

1. First quiver: at least Bowfa with crystal and an Abyssal tentacle; a ranged option is nearly mandatory. Play the NW pillar.
2. Good modifiers: Blasphemy, Frailty I-II, Relentless I, Myopia. Avoid Bees, Red Flag, Quartet, Totemic, Frailty III, Doom III, Mantimayhem III and Reentry II.
3. Every wave: start tile, frems, south spawns, reinforcements at 40 s, off-tick the pillar stack, return to start.
4. Sol: slash melee (Scythe, tentacle), dodge with the hover or L method, pray the combo tick-perfect and defend the grapple.
5. Under 10% dump Dragon claws before sand covers the area. Doom and Volatility can still kill you after Sol dies.

• 💡 On a budget your best DPS is melee (Fang); use ranged for ugly situations. With Bowfa avoid Reentry: it rags many tiles before you kill the colossus.
• 💡 Plugins: Fortis Colosseum (reinforcement timer), Better NPC Highlight (IDs 12810-12826), Visual Metronome. Turn up area sounds to hear Sol.
• 💡 Sanfew serum or the Noxious halberd special cures Mantimayhem II venom. Running pillars to survive is a trap: reinforcements kill you.
