1st: checking champions pick rate in jungle as well as their corresponding runes. - go to u.gg then search for your champion - if your champion have 0.5% pick rate or higher in 1 rank category (i.e. all ranks) but lower than 0.5% pick rate in another rank category (platinum+) then you can use the data of platinum+ to choose your runes freely. (example: https://imgur.com/a/ij0mjz1) - If your champion's pick rate is above or equal to 0.5% in both rank categories, choose your runes based on percentages. 10% pick rate is the minimum requirement to use a rune. (example: https://imgur.com/a/81TKiPY Note: the 1st number is the Winrate, while the 2nd is pick rate. Winrate doesn't matter)

2nd: Rune shards Your rune shards (https://imgur.com/a/wUQsuIz) can be chosen freely regardless of your champions' pick rate in jungle. To maximize the value you get from rune shards, here are the combinations of rune shards and their corresponding damage from your jungle pet: AS/AH AD Armor/MR - 17 damage jungle pet. AD AD Armor/MR/HP - 17 damage jungle pet. AS/AH AP Armor/MR/HP - 17 damage jungle pet. AP AP HP - 18 damage jungle pet level 1/2. 19 damage level 3.

3rd: Starting buff (these are patterns but not always true) Start at blue buff if your champion have an ability that is on short CD which also does decent damage (100 damage every 4 seconds or so is enough). Start at blue buff if you took AD/AD or AP/AP. Start at red buff otherwise. Remember to apply red buff to different jungle monsters if you lack AOE.
