Reborn Modifiers
General Modifiers
More common, these modifiers will affect broad areas. For example, you could be cursed giving you a penalty to Gold incomes from ALL Buildings. This is a general modifier because it affects ALL buildings. While it is somewhat constricted because it doesn't affect ALL Gold incomes from everything, it is still considered a general modifier because it doesn't affect just ONE thing (eg: Gold Mines only).
Targeted Modifiers
While much more rare, sometimes you are able to give something a Targeted Modifier. What this means is that ONLY that target receives the effect of the modifier. For unit groups this causes the recipient of the targeted modifier to be locked until the effect expires, this means no merging/splitting of any groups that are being specially modified (be it negative or positive modification).
For example, let's say you pay the temple to bless a unit group with +10% attack. This is a targeted modifier because ONLY the blessed unit group enjoys the affect, and should the group perish so too will the modifier.
