Unknown attribute of Gauntlet of Despair?

Wow. That's a pretty big discovery. I hope the developers pick up on this and soon; good work for finding this by the way.

Definitely an interesting find! I've noticed some other anomalies as well. EX: The on levelup buff for various characters increases their mana. However, the amount is all over the place. Some they gain more than they earned for the level, others less. This is in the BuffDefBaseStats.lua in lua/common. Regulus for example gains 64 max energy whenever he levels, but he actually receives 105 energy from the "RegulusLevelUpHealthEnergyGain". This makes little difference in game play, but it is still odd.

i knew i wasnt wrong about this item not giving me mana or something wrong with this item....

Probably.  Good find, though.  We're finding out all sorts of interesting things about the AI logic as well now that modding is enabled.  Its good to be able to dig around in the code. 

So, the item grants +350 mana as advertised.  It also grants a 7% attack speed increase (that no one really knew about - or mentioned).  It's SUPPOSED to have a 15% chance to drain 300 mana.  I don't see this in the code you provided though.  So, it appears to be completely missing...  This was one of the items that was updated with 1.2.  Perhaps a mistake was made?

I don't see anything immediately wrong with the mana tap portion. It might still be just in your head:) ( The OP did not post the entire info for the item. )

ah... there you have that then.  Thanks for the clarification.

+8 percent attack speed actually:) It probably displayed as 7 percent due to some rounding.

Anyways, if anyone is curious to check for any errors, here is the full code for the item. It is way too late for me to look for errors in code atm:)

there are a lot of things that are hidden in the lua files. did u know that plenor had 15% cooldown reduction aura ?? that is intense (morpheas discovery). check out the item modding thread, we are trying to balance out all items in the game and we need suggestion/feedback from everyone.

I noticed that one as well, but it has a # next to it both times so I figured it was disabled.

Very weird.  I might buy this item now.  Someone should make a list of all the undisplayed item attributes.

This and create a mod with correct rollover text.

Yea, they don't seem to ever actually delete anything once it is in. You'll notice that the cooldown was made before the mps increase.( It was Item 16 in the localization files, while the MPS was 20 ) However, somewhere they decided to change it, and removed the cooldown.

I was thinking of doing that. I'm betting we've all thought about doing that. I don't know about you, but I'd kind of like to know what the damage and health increases are for Rook towers, for instance. And what their lifespan is. And what kind of damage his shoulders do, for that matter.  The list goes on and on.
