This Strategy only works with a Warrior class character.*
In this Strategy you must have a Sword and a Shield**
This was done on Hard mode. It is probably smart to save after you have made all the preparations, and before you fight the boss. Make sure that its on hard as well, since its possible to go through the rest of the DLC on whatever difficulty you want, and then change it to hard right before the boss.
Add a tactic for each character
- Jerrik / Self: Health < 75% / Use: Health Poultice
- Runic Golem / Self: Health < 75% / Group Heal
- Runic Golem / Ally: Health < 75% / Group Heal
- Brogan / Self: Health < 75% / Use: Health Poultice
=====>Note: make sure that you save the stronger potions for yourself, and let your allies use the normal potions on themselves.
Have a lot of Strength and Constitution. Also a moderately high Dexterity. Have them at these amounts give or take 10 points.
Strength - 80
Constituition - 70
Dexterity - 50
[Hot Key Skills]
War Cry - Gives enemies around you a penalty to attack.
Carapace - This skill is key for defeating Harvestor Stage Two. Skeletons will not harm you, and the boss will do little damage against you.
Second Wind - To keep your stamina up.
Disengage - This one is optional, but its nice for keeping Harvestor Stage one off of you.
[Harvestor Stage One]
The first stage is the harder of the two, but it's still not a problem. There not a whole lot to say here. Some of your allies will die. Heal when you need too. Use Disengage when you need too. Just fight and live.
I would also like to point out that I used The Reapers Cudgel, which you get from traversing the dungeon. Using this it still did Physical damage while the Red Mist was present.
[Harvestor Stage Two]
This one is extremely easy.
As soon as the fight starts you will have to run from a pack of skeletons, and the boss who is now in a smaller, crawling form. You will run for nearly the whole fight.
Continue to run in a great big circle around the map. Stay near the walls. The skeletons are fast, and they will hit you while your running a few times. No worries though, because as soon as your ready turn Carapace on and go straight for the Harvestor.
Have good judgement and pay attention to your health. When you think Carapace has worn off or won't protect you anymore, start to run again. If you need health then heal yourself while Carapace is active before you start striking the boss.
This is not a long method. The Second Stage of The Harvestor should only take 10 minutes at most.
* This strategy could possibly work with other classes if substitutes for the Warrior abilities mentioned are used.
** A sword and a shield can be found in the dungeon. You can also use the item obtained in Awakening to reset your stats so that you can learn all the skills necessary, and and change your stat points to the recommended amount.
Fal1phor - Helped me to perfect this method and made the guide much clearer and easier to understand. Huge props to this guy.
