Klepto - At 20 minutes players can purchase a summoner mastery with their gold.
Unsealed Spellbook - At 15 minutes you can enhance flash to be on a reduced cooldown.
Glacial Augment - at 10 minutes, after the 5 second area slow a ward spawns in that location that continues to slow the area until destroyed. 1/1 HP Does not grant vision.
Problem with a slowing ward is they'll know that you have vision of them... Any ward that affects them will let them know. So preferably something else to help. Maybe have the rune GROUND enemies who are slowed by the effect? After like 15 minutes. That would help out a lot.
I like it a few edits I'd make.
For unsealed, "one of your primary summoners" not just flash.
GlacialI'd change to... You gain access to the "Frozen Trinket". Place a ward with 3/3 HP after a delay the area it's vision covers slows for 20%.
