That doesn't help ;-; How am I supposed to build her? I have zero idea.
Take a look at the key nodes in the skill tree and pick your niche(s). You gotta focus in PoE or you will fail in higher difficulties.
Offensively, do you want to:
- Make use of critical hits?
- What kind of damage type? Physical, Chaos or Elemental?
- What kind of weapons? Each weapon type has a specific use. Swords are more accurate, axes hit hard, daggers crit., claws heal you on hit, etc.
- Which skill gem do you have in mind?
etc.
Defensively, do you want to:
- Use armor to soak physical damage?
- Use Iron Reflex or not?
- Use energy shield? With Chaos Inoculation perhaps?
- Evade with a sizable Life pool in case you got hit? Grab Acrobatics or not?
- Use leech to replenish your life, or your energy shield? Do you want leech to be instantaneous?
- Use Mind over Matter to soak damage?
etc.
Find your niches, then go to PoEBuilder.com and try to plot an efficient path to your key nodes. Plan it using 90 skill points - it will take you a very long time to get more than that. Then link us your build and we can give you some feedback.
Some guidelines:
- In general you want 4k+ effective life (ES + Life) to survive in end-game. 3k will do too if you don't plan to run the more difficult contents.
- You don't need to focus on getting damage nodes - it's not your first priority. Most of your damage will come from leveling skill gems.
- Evade must be paired with a sizable effective life pool. Otherwise end-game enemies will one-shot you.
- Resist nodes are not really needed - you can easily go over the cap even with -60% penalty in merciless. The ones that raise resistance cap however, are good, as elemental resists are a simple percentage reduction, the more you have, the more effective it is per point.
That said, do not expect to get it on first try... your first few characters will be your learning tool. They may be able to make it to mid-Cruel and then will have trouble progressing further. At that point, take off all their gear and start a new one. Using items you collected you should be able to progress faster this time, and make a better skill tree.
Keep your old failed characters around; GGG changed the tree heavily multiple times and gave us optional full tree resets. Your old characters may be saved in the future.
