Birth mage
The Mage birthsign confers a permanent bonus of 50 points to your Magicka.

(Summary and picture from Official Elder Scrolls Site)


The Mage is the more conservative of the three magicka-boosting signs, and although it grants the lowest boost it also has no side-effects. This birthsign is useful for players wanting to create more defensive or conservative mages, or for those who want an Altmer mage without the severe weakness to magic gained from the Apprentice sign. Lastly, this sign can be used by players who want to give a non-magic oriented character a slight magicka boost for help with the few spells that are cast.
