{{as a standard action, you may cast a spell you know as long as you have a spell left of that level for that day. This is automatically successful, unless something distracts you. If there is a distraction, like weather, violent motion, or being hurt while casting, then you need to make a concentration check (the DC varies) to avoid botching the spell. Casting draws an attack of oppourtunity from anyone next to you. You can avoid this AoO by "casting defensively", but that is a distraction and theres a chance you might lose the spell. The distraction DCs are listed under the concentration skill. Whenever you try to cast a spell, you use up one spell of that level for the day, regardless of whether you succesfully cast it or not (so you have 4 1st level spells left for today). These spells can be renewed after a night's rest}}
