Ah yes at high level it's always slow unfortunately. You would have to heal poison to really gain efficiently. I'm not even sure if all poson level would work or just the highest.
In fact I think it would be easier to raise lore while taming at that level.
What you could do to be sure you're getting the best chance to raise lore is:
1- get a Crystal Ball of Knowledge
that is a quest reward given by Ortlem the Mystic in Tel Mur. He asks to bring him 100 dragon blood and daemon bones.
2-Once you get the ball, keep it in your inventory and activate it.
3- go tame pets that would be at the right difficulty to make you gain taming at 107 skill level (something that would give you 45 to 50 % chances to successfully tame at 107 taming/lore skill level).
Each time the taming check will use a skill the ball of knowledge will tell you if it was the right difficulty to gain in each skill used (taming/lore).
Adjust the taming difficulty depending on what the ball tells you, it has to be optimum (or optimal I don't remember) at best, or challenging/easy could work also. Any other difficulty level won't make you gain fast enough or at all.
If your taming level is to low to let you try and tame the pets at the right difficulty level try finding a ring/brace to raise it, otherwise it doesn't matter if you always fail your taming attempt, the only important thing is to be able to try. At each successful taming attempt there are several automatic lore checks (I don't remember exactly how many though) so each taming attempt is a nice opportunity to gain some lore skill points.
In fact I guess the ideal would be to find a pet not too dangerous, that you can "begin to tame " without too many tries but that you'll mostly fail to tame so you don't have to bother killing it or releasing/finding another one.
Except of course if you want to gain taming at the same time than lore, then find a pet that gives you optimal chance at both.
I hope this helps you, but don't worry lore will raise eventually !
I wouldn't worry too much about it, it's taming that is a huge pain to raise at high level and in doing so your lore skill will be legendary in no time without you doing anything special for it.
