So, I know that the second seal doesn't reset the level anymore, and the eternal seal will raise your max level when used at level 20, but can it only be used once per character? When you use second seal, can you apply the Eternal seal again or do you now stay level 25, not 20? I am mostly worried about how I will be able to max out my character stats this time around in Fates, assuming I can at all without needing stat-boosting items.
