Old School RuneScape Wiki

Fire Strike is a basic tier fire spell from the default spellbook available at level 13 Magic. It is the weakest fire spell available. Casting the spell alone requires 3 Fire runes, 2 Air runes, and 1 Mind rune or one may use a smoke staff to negate the cost of all elemental runes. Casting grants 11.5 experience not including experience gained due to causing damage. Fire Strike's base max hit is 8, regardless of one's Magic level.

However, if one uses an occult necklace with a smoke staff, the max hit is effectively raised to 9. This is because the damage calculation rounds down no matter how close the decimal is to the next number. 10% will make the damage 8.8 (rounding to 8) whereas 20% takes it up to 9.6, effectively raising the max hit to 9. The max hit increases to 10 if using an occult necklace, smoke staff, and tormented bracelet.

The experience gained depends on the damage dealt, the amount of experience increases by 2 for each additional damage dealt as shown on the table below.
