What are my chances?

[Squash]

What are my chances of defeating the level 191 Boss (Scarab) In the quest: Contact!?

Stats:

45 Attack,
68 Strength,
1 Defence,
70 Range,
1 Prayer,
40 Mage.

I will be using Rune Crossbow with Rune Bolts (P++)

Also, give me some tips on killing it. Remember, I have no pray...

EDIT:
Would anyone trusted be willing to do it for me?

 

[Xenophs]

Uhmmm... I don't think so.

Why not?

Maybe if you had rocktail and good potions, prayer would help so much in this scenario.

 

[Kaunietis]

Maybe if u you rocktail it would be alot easier, i think you can do it.

 

[APEX]

Your chances would be slim, but no harm in trying.

Also bring sara brews/restores if you can.

Hmm, how much above your Constit. do Sara Brews give you?

Ughh. Would anyone trusted be willing to do it for me?

With full of sara brews and restores, You can do it for sure.

you won't because sara brews on pure fail hard.
you'd better get ur prayer up than.

 

[santa11]

ur chances are low but u could give it a few tries if its a quest that u really need to do

Brews increase the hit-points no matter what the combat, what a ridiculous thing to say.

I reckon you'll do it, if not first time, the second time, it's really not that hard and 70range can be deadly.

Very low first time.
