some people mention the trees at hang garden cause they don't combo. (not true if you're not faster than them since i have to use weights to bring my chara to same speed so they combo with pets). but i do find them easy to kill and they have low-ish hp they are about 110-113 or somthing like that can't recall for sure sorry. but they are lower than pangos so if you think you're not surviving there you can try trees. if you auto walk there is also a random high lvl eagle that pops up once in a while thats likely to spawn you. (may need to walk others will likely be in the area and walks over the trees that do spawn cause its a rather small section hidden in the corner.)

leo in athens are about higher 121-130

All these can be surviveable if you have a water with you set on auto heal/rev if you have access to points to get an emote. (:\ guessing you may not but thats an easy trick to training even if you can't afford emote for yourself can try getting for a water slave only to follow you around and heal you).
Can get points by surveys or somthing (if you don't plan to use them just spam their int for heal/recover rate and con for more hp to survive longer and with about 48-60wis so they get rev or all skills what ever you prefer. also some agi to be able to go faster than you cause gear will likely break depending on where you go (if you want) don't forget to get them soul dodge and put that as top priority so they will always dodge when not healing you and be able to recover sp themselves constantly. if you do decide to make them faster have them freeze as top priority and dodge second and when sp falls below a certian # this way they will also mini busrt getting exp to lvl faster than you (but useful if they are able to survive areas with good gear even if you can't giving more boost speed or int or w/e gear you put them in.)
