Spell point

Spell Points
The amount of magical energy your character has to expend on spells before he/she needs to rest. As Hit Points are to a character's ability to stay alive, spell points are to a character's ability to cast spells. In other games, the same concept is described as Mana.

Spell Point Costs
The amount of spell points a spell consumes upon being cast is dependent on the level of the spell. The base cost is 10 spell points for a level 1 spell. For every level beyond 1, a spell costs an additional 5 spell points to cast. A level 2 spell would then cost 15 spell points to cast, a level 3 spell would cost 20, and so on.

Base Spell Points per Class

In D&D Online, characters have the option to take enhancements that offer increased spell points, beyond what is mentioned above.

Bonus spell points
Your casting ability grants you a number of bonus spell points equal to (level + 9) * (casting ability modifier). The table below gives directly the number of bonus spell points for any level and casting ability.

Note: some people have reported that an odd casting ability gave additional spell points (as if the ability modifier had an additional .5). Once this is confirmed in the final version this table will be updated.
