caster dps extra damage source, unintended bug?

[glim]

casters can melee attack while casting instant cast spells such as ruin II and bio (I'm not sure about black mage).

apparently you can get free damage 25 damage potency or so every 3 seconds if you right click the target while casting beside it. I'm almost sure that this is not intended as this could be considered another source of damage that is worth putting into the rotation.

if you are a summoner, go and try it, go to a training dummy or a mob and start spamming ruin II while you have the target right clicked at, currently my ruin II is doing 185-190 damage and while spamming it, I see another damage beside it that is hitting 65-68 damage (book attack shazam!).

oh it is also affected by raging strikes, mind you again that this is pretty much free damage source with no mana requirement, the only catch is that you have to be at melee range, which is not that much of a problem imo unless the fight has an anti melee mechanism such as ifrit and garuda. titan will be no problem, or any of the AK bosses.

Does this work with Bard+multi attack move?

Interesting but not sure how piratical it'll be for dungeons and such. It'll require you to be in melee range and would only work well with short cast or instant spells. Could be good though in some situations.

yeah, it only works when casting instant cast spells. there are bosses out there that die so fast that you don't need to conserve mana and just go ahead and spam ruin II such as demon wall, afaik, there is no penalty for being in melee range for demon wall, it's good knowing that whenever you cast ruin II, it is doing 30% more damage via book attack, or when casting bio, you get a free initial 65+ damage on cast.

free 65 damage when you are gonna use ruin II to fester on longer fights, free 65 damage whenever you cast bio, or free 65+ damage whenever swiftcasting a spell.
