Can someone explain?

how is silver ruby necklace +8 hidden strength level stronger than amulet of strength that has +10 to strength bonus

[Kagora]

Because Hidden Strength Level and Strength Bonus are completely different stats

Your melee max hit scales off of your Effective Strength Level.
Your Effective Strength Level is your Current Strength Level + any Hidden Strength Level bonuses you have (using the Slash attack Style Gives +6 Hidden Strength Level)

S0 +8 Hidden Strength Level gives the same effect as your Strength Level +8, which gives a lot more damage vs a +10 Strength Bonus

If you want an explanation of the formula you can read it here https://wiki.melvoridle.com/w/Combat#Max_Hit

I assume it's based off Runescape numebrs, so that's probably why
