Spells are the "bread and butter" of Planar Conquest.
As a Sorcerer Lord, you can potentially cast a wide variety of spells. On game creation you can distribute points into spell domains. There are 2 sets of 6 domains, (also described as 2 circles), with 1 set containing spells grouped by element, and the second set containing spells by effect. There is also a special Arcane Circle, which contains spells available to all players regardless of their spell skill distribution.
Non-Arcane Spells of tiers I-VIII belong to 1 element and 1 effect domain. Each Domain has up to 9 spell tiers.
Maximum spell tier Edit
Each point in spell domain unlocks all spells from next tier. Those spells will be available for research. You can get spells from other Sorcerer Lords via trade or as a reward after conquering world features too.
Effect domain level combines with Element domain level - maximum tier of spells that have both will be sum of those domain levels. As an example taking Protection I and Life I will give access to all Life and Protection Tier I spells and Protection Circle which is Tier II Life/Protection spell.
Please note that since all IX tier spells belong only to 1 domain, you still need 9 points in single domain to be able to learn them.
Starting spells Edit
Increasing domain tier will improve your starting spells selection.
