Trial of Will

[Lex]

This topic is old, but today I tested this side quest and have some findings to share.

My character is a Mage (difficulty: impossible) and in every battle mentioned below during tests I have 5 Archmages under my control. I must have at least 1000 leadership to start this trial.

During conversation I have two options:
1) "I would like to see what kind of mage I am. Our protective sorcery mentor, Aldares, told me that I may have some ability."
2) "I'm sure that Knight's School mentors teach us better than you sorcerers, and I'm ready to prove it!"

After selecting 1st option I have two difficulties to select:
a) Normal difficulty: battle vs 8 Furious Goblins, 9 Zombies, 6 Swordsmen (reward: 20xp, 160gp, 2 runes)
b) High difficulty: battle vs 12 Swordsmen, 8 Orcs, 10 Zombies (reward: 30xp, 230gp, 5 runes)

After selecting 2nd option I have three difficulties to select:
a) Low difficulty: battle vs 8 Furious Goblins, 9 Zombies, 6 Swordsmen (reward: 20xp, 160gp, 2 runes)
b) Normal difficulty: battle vs 8 Swordsmen, 8 Orcs, 8 Zombies (reward: 20xp, 190gp, 4 runes)
c) High difficulty: battle vs 12 Swordsmen, 8 Orcs, 10 Zombies (reward: 30xp, 230gp, 7 runes)

Case 2-Low is the same as 1-Normal
Case 2-Normal is "unique"
Case 2-High is the same as 1-High but in 2-High I am rewarded with 7 runes instead of 5

This quest rather does not depend on character level (I've tested all battles on lvl 4 and lvl 8 and got the same battles/rewards) but it could depend on class - does anyone want to test this?

I am wondering if any other person can confirm my findings: battles and/or rewards? Is 7 runes max? Or we can get somehow more?
