If you mean a skill that increases the damage your hero causes, you'd have to trigger all the damage caused with the spells and increase the variable values for each point spent in the damage amplification ability.
If you want a spell which increases spell damage taken by a target, add the item ability "Spell Damage Reduction" to the target with negative values. Remember to check "Allow negative real values in the Object Editor" under preferences and shift-click on the field in order to insert negative values.
Well if it's permanent then you could just use an Engineering Upgrade sort of thing. If not then Spell Damage Reduction works well (I think, been awhile since I've done something like that)
I think we need to add something to the bottom of the front page that shows the Headline News forum that has a link to go to the News Forum Index so people can see there is more news. Do you guys see what I am saying, lets say you read all the articles on the front page and you get to the end and it just ends, no kind of link for MOAR!
Finally finding about some of the bots that are flooding the users online - bytespider apparently is a huge offender here - ignores robots.txt and comes in from a ton of different IPs
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
