Most players relayer weapons with strength like BC/Titan hammers or SOT. It is known that Titan hammers have 15 str and give more hp than all other relayers, except grand auction Ancient Titan Hammers which are very expensive. Also if you have high +Enhanced potion from relayers, then each 25% of EP will give 7.5 bonus hp for 2 minutes after drinking greater strength potion.
I don't have too many Titan Hammers lying around so I tried other type of relayer: ecru citrine ring. These are crafted rings that have interesting stats and can have +8str, +5 hp, 75% enhanced potions + dex/sdi/etc.
So one Titan hammer relayer with 15 str bonus give +30.5 hp, or +38 hp if you put 25% Enhanced potions on it and drink greater strength potion. And ecru citrine ring give +17hp base, or +39.5 hp if you drink greater strength potion.
I relayered 5 of these rings month ago and want to share how it works.
This is example of ecru citrine ring relayer.

So without potion, ecru citring ring obviously gives only 17 hp which is quite low, but I still have 513 hp in my suit which is enough for 98% content on shard. And if I drink potion, I have 708 hp which is better number and can help to kill those few hard-hitting mobs. Of course it is not very convinient to drink potions that last 2 minutes, but I have hotkey for removing shield, drinking potion from keg in HBOH and wearing shield again which works fast enough. With current content I only drink potion for hydras in Prism of Light, minos in Labyrinth, Flesh Eating dragon in Bedlam, maybe for Toxic Elementals in Paroxy Palace, for one mob in fel Wrong dungeon, and sometimes in s'gail for big groups of mobs. It helps to have higher hp noticably in these places, and 2 minutes that one potion lasts is enough to kill most dangerous mobs.
Of course I'm not saying that these ring relayers are better, because with Titan Hammers less need to drink potions, which is convinient. But these relayers are way cheaper and now I have little motivation to change these ecru citring rings to Titan Hammers. Maybe only for mana/stamina bonus, but I don't lack these stats in my suit in practice. Especially if ring additionally has SDI(12-13% max I think) and dex bonus.
These rings are quite expensive to craft because each ring requires 10 ecru citrine gems, and really good rings are crafted rarely after ton of gold spent on gems. I didn't measure but I think each ring costed me 200-400ed to craft which is notable sum, but still way less than 2k ed for Titan Hammer, which also needs removing arty tag, levelling, and even then titan hammers are rarely being sold on market.
Of course I hope that more content will be added, and better Titan Hammer relayers will be really needed, but as of current content, I have little trouble killing all existing mobs with my suit.
