Upgrade Info

Are there any good tutorials on working and messing with upgradedata and upgrades? Looking around I found a few useful tidbits, but in general I'm not too sure how you mess with these different upgrades (not only ones that boost dam/armor, but hp/atk spd/mv spd). I'm not sure how to phrase all the little questions I have about messing with upgradedata, so a nice tutorial would be nice ;D

There is no tutorial for that as far as I know. But I am planning to create an upgrade modifier list, which lists all the IDs and their effects. You can look at the modifiers of other upgrades (especially the comments are useful).
Example: rhpx is the "Hit point add modifier". So if you want an upgrade that adds HP, write rhpx into the effect<n> (without the brackets, where n ist the index; n is for example 1 => effect1) column. Into the base<n> (ýou know what n is...) you should enter the value. In the case of rhpx this is the amount of HP added through this upgrade. The mod<n> column is only needed if your upgrade has levels.

Howzat? Can you just keep hauling in column data for additional levels?

For the levels you have to enter values into the mod<n> columns. This is the value the base<n> will increase at each level.
Example: base=100, mod=10; l1=100, l2=110, l3=120
