Enchanting HP to items

Hi all,

in the past I enchanted many items using ref gems and a very high kill count to get a good value (always above 100 with ref. violet gems, range: 60-109).

But this method does not work anymore. Is there any other "trick" with enchanting hp or is it completely random?

thx in advance

It is random..

But i usually get a bad enchant if I use 2 gems after eachother.. the 2nd one is a bad one..

But I have SDG enchanted all my items (except necky which is 184 from sup violet) the SDG enchants i have are 238+.

I use 1 SDG and then i have to wait a while, a week or 2 before i had the money to buy the next one.. Then I tried again, and got a high enchant..
