Apologies. Don't know the official terms for this stuff. Anyways...
Dual Attack / Dual Guard stuff:
Dual Attack
- If the main attacking unit is unpaired, a nearby unit will assist, dealing a single strike at half normal damage if they hit.
- The supporting unit may be chosen at will.
- When defending while unpaired, a nearby unit may only assist if the main unit is capable of attacking.
- The assisting unit will be chosen automatically based on support level.
- Speed does -not- affect whether the supporting unit may attack twice or not. This makes strong units really helpful offensively, even if they are slow.
- The supporting unit may be Paired Up and will still assist.
- The range of the supporting unit does not matter. Berserkers may hit you from three squares away. It's funny until baiting a sorcerer with a ninja causes his axe-wielding friend to come over.
- Weapons with the Silver effect do not activate for the supporting unit.
- Weapons with the Devil effect and Brave effect do. Others I can't personally confirm.
- Dual Attacks will always be negated if the target is Paired Up.
Dual Guard
- Requires using Pair Up.
- Any main attack dealt or received while Paired Up will up the shield gauge by two.
- When the shield gauge is full, the next main attack received will be negated.
- Supporting attacks will always be negated and may not add to or deplete the shield gauge.
- The shield gauge will deplete slowly by a rate of two for each turn of inaction.
- You may not use Dual Attacks while Paired Up, though you may still assist other unpaired units when they're attacking.
That's it off the top of my head.
Personally, I use Dual Attack a lot. It's much more flexible as I can easily switch to Dual Guard if I need it on the next turn without any penalty. Dual Guard meanwhile is inflexible. You're more or less locked into it once you're in it. Something of a last-ditch mechanic for me since if the situation suddenly calls for more offense, I just can't bring it.
I had a unit miss with 91% earlier: they had to have changed how hit rate works.
I've been hit by three Berserkers in a row at sub-30% one time for an instant game over. Paralogues are supposed to be easier, but they seem to have a thing against me. >.>
But yes, the percents are actually accurate this time. You'll (usually) appreciate this as enemies will typically have accuracy above 50%.
