# Does the half-level modifier contribute to damage?

Taking a random spell, I find Flames of Phlegethos. Its hit is `3d10 + Constitution modifier fire damage`. Let's say the caster has a constitution score of 16, and he is level 2. This means his constitution modifier is +3 from his constitution score, and he has +1 from his half level.

Would his damage on this spell be `3d10 + 3` or would it be `3d10 + 4`? The PHB doesn't seem to clarify this. Thanks!

Welcome @James! Luckily this question has been asked and answered before, so I've closed your question and merged it over to this one. –  mxyzplk Jul 22 '12 at 1:09
Half-life (t1⁄2) is the amount of time required for a quantity to fall to half its value as measured at the beginning of the time period. While the term "half-life" can be used to describe any quantity which follows an exponential decay, it is most often used within the context of nuclear physics and nuclear chemistry—that is, the time required, probabilistically, for half of the unstable, radioactive atoms in a sample to undergo radioactive decay.

@Lohoris Ummm, this is about "half-level" not "half-life". But umm... thanks I guess? –  corsiKa Apr 14 at 15:20
Yeah, it was just an half-assed joke. And this is another one. So we basically have one full ass, I guess? –  Lohoris Apr 14 at 15:22

No.
Ability modifiers are applied to damage, but half-level isn't. So, in your example, the Flames of Phlegethos would inflict `3d10+3` damage.

Half-level is applied to attack rolls because they are ability checks. As a more general rule, feel confident to add half you level to every d20 roll except saving throws and to every static number which usually stands against a d20 roll (like defenses).

No, it doesn't mean that.

In cases like the melee or ranged attacks, your relevant ability modifier (strength or dexterity) gets added to the damage, but there is no mention of your half-level. There doesn't really need to be either since as you're going along, you'll be finding more powerful weapons anyway (or weapons with +1's).
