	The override skill can be fairly simple, just like the Target_DummyTargetSkill that we use in a couple of cases. However, it's advised to make the override skill as accurate as possible. E.g.: for a Summon skill that spawns a summon that does only fire damage you shouldn't use an override skill that only does physical damage. Ai might then cast the summon in the middle of a group of enemies that are all immune to fire damage. Use a target skill that represents the actual summon as accurate as you possibly can.

	===Scripting===		===Scripting===
			Overriding Ai with scripting is relatively easy: make sure the priority of your REACTION is higher than 60 (higher than all REACTIONs related to Ai) and the Ai won't execute anymore.

			Sometimes you'd like to make sure Ai prefers a target, or doesn't, or even totally ignores a target. There are some tags you can set on objects to make it work:
			<ul>
			<li>AI_PREFERRED_TARGET: boosts any score on this target. This will not only increase being attacked by enemies, but also being healed by allies</li>
			<li>AI_UNPREFERRED_TARGET: decreases any score on this target. This will not only decrease being attacked by enemies, but also being healed by allies</li>
			<li>AI_IGNORED_TARGET: completely ignored by Ai. Damage doesn't matter, healing doesn't matter, killing doesn't matter.</li>

-Ai 2.0 or, as we'd like to call it, <b>Jane</b> (used to be an abbreviation, but we already forgot about it the next day) no longer uses a script for every single skill to reason about its usage. Almost all logic has been moved to code, and all that's left in script is starting the Ai calculation, stopping the Ai calculation, and executing the action that has been selected by Ai. This script logic can be found in DefaultBehaviour.charScript. The Ai now takes into account the properties of a skill, the statuses that are applied, the weapons that are used, the items nearby, etc. It (attempts) to simulate what's going to happen if it will use a certain skill at a certain target and assign a score to it. The action with the highest score will be executed. All this happens automatically, so a new skill or status can be used by Ai without any extra steps. Of course, there are exceptions, and you'd still like to guide or override the Ai from time to time. That's what this page tries to cover in detail.

	The last skill conditions are the difficulty modes. These are simple checkboxes to enable/disable a skill on a certain difficulty. The very last thing on the list, the score modifier, is exactly what it says it is: a score modifier. If you want the Ai to use a skill more often, even if it's not that good at all, you could increase the score modifier. You could also use to, for example, force Ai to cast a certain skill after an event: set a high score modifier and set a source tag condition for a tag that you apply via script.
