Level limit has a formula that is the host's (whoever is the human target being invaded or summoning allies) level +/- 10%, rounding up.
For example, a SL 30 host will have the following level limits:
30 * 0.9 = 27
30 * 1.1 = 33
So if you're a level 30 host, you may summon or be invaded by players that are anywhere from SL 27 to SL 33.
[/quote]That's wrong. Its not based on the host's level, it matters on who puts their sign down / invades. Furthermore, that level range range is incorrect.
If its a darkwraith that invaded, then to invade a level 30, the darkwraith would be level 1-33. Darkwraiths can invade 10% lower or up to infinite levels higher.
As for the whole summon thing, the level of the summons could be from 19(18 if it rounds up) through 44. White / Gold summons are +/- (10 + 10% of their level).
I'm too lazy to explain the other covenants.
