Wait, what speed? If you mean the speed at which projectiles travel, that would only apply to Fireball and Claw, right? Because well, Iron Fist is a punch, I honestly wouldn't know how to quantify the speed of a punch... Or of the spark of a match for that matters o.O
EDIT: nevermind read the rules again. Speed added. Although I should point out, the topic with the rules on the spells has the new rules (with the speed), but still the old template (without the speed).
