This came up a while back, I just had to compile some information before starting a thread specifically about this.

The basic question is that aside from favorites, how much do material costs weigh in on the decision for which skills to level? In most cases the material costs are pretty reasonable, but there are extreme cases where they might affect your decision for who to prioritize skill leveling.

~ Gold rarity materials all cost at maximum 10-15 per skill except for two exceptions:

- Hearts: Jeanne and Amakusa both require 20 hearts per skill
- Dawn Cores: Qin Shi Huang requires 20 Dawn Cores per skill

*So basically some 5 star Rulers are the exceptions here.*

~ Silver rarity materials all cost at maximum 20-24 per skill except for again two exceptions:

- Seeds of Yggdrasil: Arjuna, Iskandar and Tamamo-no-Mae require 30 seeds per skill
- Knight Medals: Maybe due to not many servants requiring them, several requre 30 and 40 per skill

## Knight Medals

*The format is the total per skill, and then in parentheses the amount needed at each skill level.*

40 (Lv7:10/Lv8:30) - Brave Liz, Summer Okita

30 (Lv6:10/Lv7:20) - Arthur Proto, Summer Artoria Alter

30 (Lv4:10/Lv5:20) - Artoria Lancer, Astolfo Saber, Bradamante, MHXA

~ Bronze rarity materials are where the really extreme examples are, the maximum per skill varies from 48 to 72 depending on the material. Iāll list all the ones that cost 30 and higher since 90 for all three skills is a significant amount.

*For all of these the format is the total per skill on the left and in parentheses is the skill level the materials are needed, if split between two levels the cost is shown for each level.
They are listed in order of highest total followed by highest amount per skill level followed by highest skill level.
The basis for this order is basically how much the material cost serves as a barrier and how essential it is to use your materials on that.*

Feel free to discuss who you think is worth it and who you think the material costs are a decent case for not leveling their skills past a certain point for a long time or possibly at all.

Or you can just lament how many materials you need for your favorites, thatās fine too I guess.

Starting out the discussion, I think Benkeiās costs are a very good reason to not level his skills past level 7 based on his kit and the sheer amount of Void Dust he needs for skill level 8.
