About this converter
Halo 3 hides nine gold skulls that raise campaign scores. Iron pays the most at 3x but restarts the level when you die solo, or sends co-op teams back to the checkpoint. Famine, Tilt, and Mythic each pay 2x. Black Eye, Tough Luck, Catch, Fog, and Thunderstorm each pay 1.5x. Four silver skulls (Blind, Grunt Birthday Party, Cowbell, IWHBYD) change the game without changing the score, so they sit at 1x. Skull multipliers stack with difficulty, style, and time bonuses. Values here are the original Halo 3 (Bungie, 2007) figures.
How to use it
Pick two entries and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 Iron against 1 Mythic to compare the top gold skulls. Amounts here mean score multiplier, so 3 means triple points on every kill.
Later games rescaled skull math. Tables for later titles list smaller multipliers such as 1.1x to 1.3x for the same skulls, so this page fixes Halo 3 values and says so in each note. Silver skulls grant no bonus and are included at 1x so players can compare the full set of thirteen. Skull effects also raise the challenge: Famine halves dropped ammo, Mythic doubles enemy health, and Tilt doubles enemy resistances.
FAQ
Which Halo 3 skull gives the biggest multiplier?
Iron at 3x. It restarts the level on solo death, so the bonus comes at a real cost.
Do silver skulls raise the campaign score?
No. Blind, Grunt Birthday Party, Cowbell, and IWHBYD sit at 1x. They change the game without changing the score.
Do skull multipliers stack with difficulty?
Yes. Skull, difficulty, style, and time bonuses all stack. Max scores need Legendary, fast clears, stylish kills, and all nine gold skulls.
Are these values the same in every Halo game?
No. These are the original Halo 3 values. Later titles rescale the same skulls to smaller multipliers such as 1.1x to 1.3x.
