Honestly, trying to read the dialogue going on here where everyone tries to figure out how intimidate works is painful, so I'm just going to lay it out so that everyone knows. Hopefully Dulrik can read this and decide what to do. I've
already laid out this problem
in the past with no response from Dulrik back when he was less active, so it's clearly just flown under the radar until now.
***BEGIN CURRENT IMPLEMENTATION OF INTIMIDATION***
As things currently stand, intimidate is checked if someone tries to take an aggressive action against a hellion's group in the same room as long as the hellion is A) not resting, sleeping, or stunned and B) not -personally- engaged in melee combat. A hellion is not considered "personally engaged in combat" unless he is getting strikes with a melee weapon on a target each combat round. You have to pass an intimidate check for EVERY SINGLE ACTION taken against a hellion's group as long as the hellion is not personally engaged in melee combat. This means that if you are fighting someone in front of a hellion and you try to bash your target, you have to bypass an intimidate check if the hellion in his group is not personally engaged in combat. It also means that if you hit a 9 man group with color spray and a hellion is in the second or third row of that group without a reaching weapon on, then you have to save against 9 intimidate checks. The same is true for any group affect spell, and also for offensive staves that target anyone in a hellion's group.
If you ever fail any intimidate check against a hellion, then you cannot take any aggressive actions against the hellion or the hellion's group at all unless A) intimidate wears off or B) the hellion engages in melee combat. If you attack a hellion's group while intimidated, but the hellion has engaged in direct combat since you failed your intimidate check, you can act freely against the hellion and his entire group unless the hellion ceases to be personally engaged in melee combat.
***END CURRENT IMPLEMENTATION OF INTIMIDATION.
Now, the question is whether or not this is currently overpowering. I personally think that it is, but not for the reasons that most people are stating. I love the way that intimidate works now. I do not, however, like the idea of a hellion being able to sit in the second rank without a reach weapon on, or in the third rank at all, and still gain the full effects of intimidate. As things stand now, you can literally bypass one intimidate check to start stabbing a second-rank hellion in the face with a spear, but then try to trip him and get intimidated just because the hellion isn't wearing a reaching weapon. In the same way, a hellion can sit in the third rank spamming spells without a reaching weapon on while still forcing every single skill or spell used against his group to require an intimidate check, and no matter what, you are eventually going to fail a check.
I propose that intimidate, if possible, be refactored slightly. If a hellion is front rank, intimidate should work just as it does already. If a hellion is second rank and wielding a reaching weapon, intimidate should also work just as it already does. Auto assist should not factor into this at all. However, I think that if a hellion is in the second or third rank without a reaching weapon, he shouldn't ever incur any intimidate checks because it's impossible to force a second or third rank hellion with no reaching weapon on to personally engage in combat.
I think that if a hellion -can- be engaged in direct combat if someone were to hit him with a direct attack or spell, then the onus should be on his enemies to engage the hellion, or the hellion should have the liberty of engaging whenever he wishes. Allowing intimidate to be bypassed if anyone in the hellion's group is fighting will all but remove every useful application of the skill. How useful would sanctuary be if it all that it did was prevent people from attacking your character if your group wasn't already fighting? As well, making intimidate work only for those people in the hellion's group that aren't currently in combat is in my opinion nonsensical. Why would you be scared to petrify a sorcerer behind a hellion, but not scared of the barbarian in front of him? I also like my solution because it allows intimidate to still be useful while also removing the way OP'd nature of it.
