Holy is one of many spells. It requires level 15 to unlock, and costs 30 mana to cast. At higher levels, it increases damage, duration, and size. It looks like a yellow laser starting from the player and going forward down the lane. The size bulges in and out; the size/width column below is the smaller of the two sizes of each level.
|Level||Base Damage||Damage from Intellect||Duration||Cooldown||Size/width|
|1||11.5||.25||5.5 seconds||30 seconds||smaller than lane|
|2||30||.6||5.5 seconds||30 seconds||lane|
|3||60||1.2||5.5 seconds||30 seconds||lane|
|4||90||1.8||5.5 seconds||30 seconds||larger than lane|
|5||120||2.4||5.5 seconds||30 seconds||larger than lane|
|6||150||3||5.5 seconds||30 seconds||much larger than lane|
Each upgrade level costs 15000g, the same as the base. Level 6 costs 75,000g or double the cost of the previous level.
Despite the levelling up saying that the duration would change, it stays at 5.5 seconds for every level.
