SULFUR Desert Santa Boss: Full Fight Strategy Guide

Bring a sniper or an assault rifle plus a large supply of bullets — that loadout is the key to surviving the Desert Santa fight, which takes place on the final level of the Desert, the area you reach after beating His Most Holy Emperor in the Shav'Wani Fortress and jumping off the cliff. According to the SULFUR Complete Guide and Walkthrough on Into Indie Games, the battle happens inside a moving dome of sand and runs through several distinct phases.

Desert Santa fight walkthrough

Before the fight, check the Desert basics: it has five levels with the amulet altar on the third, Hellshrew drulers and snipers hiding as plants on the roads, and optional Crypts that only need a Crypt Key if you want inside. Repair items are worth bringing, since the fight is long and drawn out.

1. Phase 1 – sand jumping

   Shoot the boss while he jumps in and out of the sand. Around 20% HP lost, he starts summoning enemies: rides burst from the sand and enemies jump off into the arena. Clear them while he keeps jumping.

2. Phase 2 – rockets

   Once he has lost about 30% HP, he calls down rockets. Stand away from the markings on the ground — some salvos cover the whole arena except one row. The dome itself moves during this stage, and leaving it damages you.

3. Phase 3 – sniper duel

   At roughly 50% HP lost, the boss equips a sniper rifle and vanishes from the dome, which now drifts toward nearby ruins. Watch the ruins for his silhouette or the origin of his laser sight, shoot where you predict him to be, and use the pillars to block his shots. The fight resumes normally once the dome reaches him or you deal enough damage.

4. Finish him

   After a huge ambush of enemies, the boss demands a one-on-one fight. Just keep shooting until his HP empties.

The Desert Santa drops several gift boxes; attack them to reveal the items inside. Afterward, walk out of the arena in any direction to reach the veil — the game warns you cannot return, so use your amulet to go back to the church and prepare first.
