Razorscale - Ulduar boss guide

Tactics for Razorscale in Ulduar 10/25 for WoW 3.3.5a: harpoons, waves of iron dwarves, Lava Bomb, ground phase with Melting Armor and full loot.
Review
Sharpwing is Veranus, the proto-dragon ancestor from the Storm Peaks: Loken captured her, and Ignis riveted iron plates to her skin. An optional boss without hardmode, usually comes second or third. While the expedition dwarves repair the four harpoon cannons, the raid fights off waves of iron dwarves from the drilling machines under fireballs and Lava bombs from the air. As soon as the required number of harpoons are fired, she is chained to the ground, the Burst window. Below 50% it sits forever: tank swap on Melting Armor and race with stacks of Flame Strike.
- The battle starts through a dialogue with the expedition commander - there is no trash talk in front of the boss.
- You need 2 harpoons in 10 and 4 in 25 (REQ_CHAIN_COUNT in the script): as soon as there are enough, the boss sits down and stands for ~30 seconds.
- Lava bomb (blue ball) is the main reason for wipes: run out instantly, not to be confused with the Fireball (it will arrive in any case, there is no point in running from it).
- Achievement “Clean Shave”: take down the boss in no more than 2 air phases - press hero on the first landing.
- Achievement “Iron Dwarf, medium-rare”: expose the dwarves to the boss’s Fiery Breath on landing - the tank turns the adds into a cone.
- After each takeoff - Wing Cleave: scatters everyone, be prepared to run back and intercept the adds.
Combat phases
The boss hangs in the air and is invulnerable (all damage to her above 440 in Z is reduced to zero). Every ~45 sec, 2–3 (10) / 2–4 (25) groups emerge from the drilling machines: Dark Rune Guard (Storm Strike), Dark Rune Sentinel (Chain Lightning, kicks) and sometimes Dark Rune Sentinel (Whirlwind - one-shot of rags). They fly in parallelFireballs every 4 sec and Lava Bombs every 13 sec. Dwarven engineers are repairing harpoons - protect them.
- Protecting Engineers
- Kick Chain Lightning Marines
- Range focus on sentries
- Run out of Lava Bombs
The boss falls and remains chained for ~30 seconds. All dps goes to her, all cd and hero. After 30 seconds she warns with an emote, blowingFire Breath and takes off withWing cut, scattering the raid. The cycle repeats until you hit 50%.
- Full burst of all CDs
- Fire Breath before takeoff
- Wing Cleave = spread
Below 50%, on the next takeoff, she instead remains on the ground forever (emote about permanent landing), drops aggro and runs to the farthest target - the tank needs to be taunted instantly. Further:Fire Breath cone every 20 sec, Lava Bomb every 13 sec,Melting Armor on the tank every 10 sec andFlame Strike on target every 7 sec. The adds don't come anymore.
- Instant taunt after landing
- Tank swap for 2 stacksMelting Armor
- Kite in a circle from Lava Bombs
- Race with stacksFlame Strike
Abilities
Positioning
Phase 1: the raid is divided into 2 groups (10) or 3 (25) - a group per drilling machine spawn zone, each with a tank and a healer, people scattered 10+ meters away. The harpoons are behind, the assigned DPS is running towards them. Phase 3: The boss kites in a circle along a line on the floor, range in the center, miles on the inside.
Role Tips
- Take the sentries (Whirlwind) away from the raid right away - this is the only add that really kills.
- On landing, turn the adds into a coneFire Breath: and the damage is free, and the “Iron Dwarf, medium-rare” achievement will drip.
- P3: after a permanent landing, the boss drops aggro and runs to the farthest one - the taunt must be ready in advance.
- Swap for 2 stacks, not 4: at 5 stacks, Molten Armor immobilizes you right under your breath.
- Keep the raid at the top: death is almost always from a bunchFireball + Chain lightning, not from mechanics alone.
- Discipline with Barrier is the strongest choice in P1 due to the constant random damage.
- Healing the DPS running towards the harpoons is a separate task; he remains alone, away from groups.
- P3: under 4+ stacksStrike the flameThe damage to the tank grows like an avalanche - keep a large CD towards the end.
- Range by sentries, miles by guards - not the other way around: Whirlwind one-shots miles.
- Throw kicks at the Marines' Chain Lightning - it hits up to 5 targets with increasing damage.
- Hiro - for the first landing: the goal is to reach 50% in 1-2 air phases (the "Clean Shave" achievement).
- Blue ball under your feet - cast and run; Dead DPS does no damage.
