You need to build Magic Guild Level 3 (pre-req: Combat level 10) in order to have level 3 spells; but that alone does not grant you the use of those spells in battle. To cast it, you also need to have basic chaos talent, which will allow you to cast level 3 chaos spells (and also increases the damage).
Another alternative is to learn the wisdom talent, which will grant you access to all level 3 spells available to your faction, provided you have built Magic Guild Level 3. |
