I found her the first time exploring after leveling up once on day 9 by mistake, i usually make the strongest possible lv 0 charakter and grind exp to lv 100 to save a LOT of time and actually getting something from goblins
that's a clever idea honestly, the only problem i see is knowing how much exp you need for that
uses Cheat Engine to get infinite XP after about 5 fights and hits level 185 on day 4 or so Yup, great idea. Totally takes forever though.
proceeds to also get infinite stat/skill points and has a FULLY maxed character at level 0 For stat points you need to be in NG+ so you can start with stat points, but otherwise...I can get maxed pretty much instantly with some luck. I'm a dirty cheater...I do have a legit character on the mobile version where I can't cheat, but...it's a lot slower.
Best way to get XP at low levels, as far as I've seen, is to max what you can, and then use the arena. If you get as much power as possible before you try, you can take on the first or second solo fights. Blind and Heal are must haves at minimum, and it's great if you can get the strongest equipment available, but if you can swing the first or second (or third, if you're really confident) fights, you can get MUCH better XP than a little goblin/imp.
A level 0 taking down the second level of golems gives about enough XP to go straight to level 5 (almost 1500 from a single fight) but usually you can only do 1-2 a day (or every 2-3 days) depending on just how bad you get beat up. With luck, you can end the fight with enough health for another fight.
For the golems, my usual strategy is to use a 0 corruption character with the Beautiful Sword. I don't know all the weapons available, but it's easy to obtain, and stronger than a good chunk of low level weapons. Then I blind, charge, normal attack, blind as needed, and charge a second time, if the fight's not looking like I can hold back. I'll often (at level 0) end up needing like...2 days of rest to recover my Health/Mana for almost every fight since I have no regen yet. Getting toughness up high enough for the first level of regeneration with the free perk point you get is a decent idea.
Of course, that all is for if you're not playing a higher difficulty (I usually try to play MC difficulty, I do basically nothing to imps and gobs until 50+ strength, and even then it's still risky. I always pick Speed when creating a character to maximize running and dodging early on). On the higher difficulties...Goblins and Imps ALL the way if you want to max a level 0, and only after you have a lot of stats already. Avoid fights for as long as possible. Early on, Forest is the best money maker. Honey and Chitin sell good, and once you can kill imps/gobs, their ears/skulls also sell well.
Anyway, that's just how I play.
I can't find electra. Is the wiki information still current?
Electra is the Raijin, right? You need to be able to go to the Mountains or High Mountains, I can't remember which, and she only appears after you've met her there. After a certain point, again not sure when, she starts appearing pretty much anywhere. I could be wrong, I don't really pay attention unless I'm trying to recruit her. Otherwise I just run every time I see her.
