The REAL IP cost to EVERY Tier 3 rune in the latest version of League ( not an estimate)
I had calculated it as correct as it'll be, and for EVERY Tier 3 rune, 3 quints per stat bonus, 9 per seal, mark, glyph, it adds up to at least over 400k IP (even with the new reductions in cost), and sums a whopping 413901 IP!!!
There are 99 Quints, 216 Seals, 198 Glyphs, and 171 Marks in our current League Version.
Mini Tidbit: I have a literal total amount of 7 runes left to purchase. 1 quint of scaling health regen and 6 health regen glyphs.
I was wondering how many mains have collected EVERY rune in the game, as it should be quite a limited club.
