can i get back the points that i used on other abilities such as knowledge etc . how comes i cannot use any spells in elves though they have 1 knowledge
For elves, you need to reach combat lv5 and build magic guild 1 in your castle.
Elves can cast nature and holy spell, u can check lv1 to lv4 spell here. https://www.lordswm.com/help.php?section=31
