1. It's not impossible, but you're looking at a lot of baskets, a few apples, and some decent gear and a decent level 64 knuckle (scrolled). I had to redo it a couple times before I got the hang of it (I went in with 1 apple and it wasn't enough wahwah). 2. I don't think there's any difference as far as MM or BM if you're going to bloodwash because it's all about that dank SE, especially since you can always get a mount to compensate for the speed boost if needed. 3. It is not possible to farm stoppers with an SE mule. I had about 300 base int and the rest in dex on my BM that I actually planned on playing and I wasn't able to 1h until I washed most of it out even with atk gear and a perfect bow. Furthermore, at 134 you wouldn't even have enough SP for max Phoenix since your first 30 sp 120-130 would be spent in SE. 4. It's possible, but not recommended as you have to watch out for seduce for your hero while also making sure you don't get dispelled. Without ~bosshp I recommend it even less. I think I only bothered to do Hero + SI when I was dual clienting HT. 5. No idea sorry!
I have a SI mule too. I didn't put any point to HP before 3rd job advancement (not sure if i reserved some ap or not), and when i was done doing job adv I put all the AP to HP. Now it's 126 and has around 22000 HP. So you don't need to be worried about not having enough HP if it's a mule. How would SI buff u by 50%? The speed factor for swords are 0.63 (2), 0.69 (3), 0.81 (4), 0.84 (5). In the dmg formula, take the reciprocal of it.
1. Not too difficult if you have acc potions like amorian baskets or maple pop, onyx apples or stoppers & items that give you your primary stats (this is because attack scales with your primary stat) 2. I think it's just preference since its just a mule for SE 3. attack scales with your primary stat so probably not.. might be possible at the jacko boxes (the map next to voodos) 4. It's possible 5. idk
For my ST hero, SI gives me about 9.5% buff (0.69/0.63=1.095). I am usually too lazy to bring it lol. Now SI has no effect on meteor/genesis so it's pretty much a fm mule for me.
I personally feel like it might not be worth the time and effort for a ST hero. Most people who have SI mules have Claymores or plan on using Claymores and/or made them before when it worked with mages as mentioned above.
You're going to have base dex either way since stats are capped at 999 now xD If you really want to go claymore, then I certainly won't stop you as I also have one, but a perfect claymore has a pretty high demand and very few people are selling them so it might be hard to get a hold of (and expensive even if you do manage).
They certainly are useful, but unless you're getting a lot of benefit from them, you have to also realize you'll be losing some dps just by having to move that char and having to rebuff each time as well. You'll probably need some time to get used to dual clienting in general as well too ^^ I'd maybe wait and see what HT is like first before deciding if you want to make an SI mule or not haha
