You are good at focussing your mind.
Check: you a Concentrate check whenever you may potentially be distracted while engaged in some action that requires your full attention (such as casting a spell or making a Tinker or Treat Injury check). Situations such as taking damage, working in a bouncing vehicle, or dealing with severe weather can require a character to make a Concentrate check (as per the Concentration skill description in the 3.5 PHB). If the Concentrate check succeeds, the character may continue with the action. If the Concentrate check fails, the action automatically fails (with the appropriate ramifications, if any), and the action is wasted. A successful Concentrate check still doesn't allow a character to take 10 when in a stressful situation; he or she must roll the check as normal.
| Concentrate DC | Task |
| 15 | Avoid attacks of opportunity when attempting a skill check that normally provokes attacks of opportunity |
| 10 + Power points expended | Cast a spell with a somatic component while wearing armour you are not proficient with (armour check penalty applies) |
