All philosophers, regardless of level and class, can perform some basic actions in combat:
Attacking is a standard action that tends to be the focus of a Philosopher’s turn. For a basic attack, a player rolls 2d6+CRE. If the result is a two, the attack fails completely, while if the result is a twelve, it ignores enemy defence. Attacking in this fashion deals damage equal to your CRE minus any defense the enemy may be attempting.
Defence reduces CON+1d6 damage from attacks. Each turn the Philosopher will automatically defend against the first attack targeting him each round. During the Philosopher’s turn, he may choose to defend, however unlike attacking this consumes the Philosopher’s full turn and they may not take any other actions that round; any attacks directed against the Philosopher will take the same CON+1d6 penalty associated with the initial attack, until the beginning of the Philosopher’s next turn. Unless you have a skill that states otherwise, you may only defend yourself. Ongoing damage cannot be defended against.
Similarly to attacks, a natural roll of 1 negates the defence completely and a natural roll of 6 negates the attack completely.
Every Philosopher of Deixis has the ability to heal, at least to some extent; instead of choosing to attack or defend during his turn, the Philosopher can heal an ally [though not himself] of 1d6+CON damage as a standard action.
Summoning a Plot Element counts as a standard action on their turn. The summoner may dismiss an Element during his turn as a free action.
Preforming an action not related to combat that requires a challenge roll, is normally counted as a standard action. Looking around the area for objects or an escape route, trying to negociate with your opponents, and trying to run away all consume your turn.
