What exactly does the special ability do?
If it casts a spell, then it cannot be implemented at the script level.

Ideally, of course, it would be best to remove Railag and give Arafel -1 initiative to enemies per level. But any slowing down of enemies would be suitable for her.

But you won't do that.

In general, of the two latest bios, I liked Dyrman's more.

My more extensive version didn't work out, although it could be combined with the fact that the jug shattered. In general, I've already written it.

Draylana was one of the daughters of the high druid in western Irollan and, even as a child, was distinguished by her curiosity and inclination towards magic. Once, she sneaked into the sacred grove of the druids, where she had a strange vision: a jug that shimmered with incredibly beautiful colors and mysterious writings, which were incomprehensible to the girl, but which struck a chord in her heart.
Draylana left Irollan and began her journey in search of knowledge about the cherished jug. She joined the sea elves, where she studied the knowledge of the cult of Shalassa, then wandered in the "barbarian" lands in the east of Ashan, studying healing and the culture of the inhabitants of those places, where she collected bits and pieces of information about the cherished jug. Once, fate brought her together with a traveling mage, who told her about a relic hidden in the depths of the elven forests – a jug with an inexhaustible supply of mana. Without a moment's hesitation, Draylana set off back home.
Having found the jug, the elf touched it, after which it shattered into many fragments. It turned out that this was enough to gain the ability to restore mana during lulls, which helped in the fight against the undead that had flooded Irollan.
Now she leads one of the border armies of Irollan, without losing sight of the goal of finding the great artifact of her ancestors.

Special ability: Replenisher – complete mana restoration for each won battle.

I think this is the best option.)))
