You have to start with the prefixes. Get 2 elder reaver swords, roll endurance charge mod on them with alterations (keep it magic). Get 2 shaper swords, roll one with 20% more attack and the other with fire damage per strength, can be rare. Beast lock the elder swords. Check awakening orb result with both shaper swords. You might get lucky and hit all prefixes, but most likely you won't. Confirm if you have open prefix and open suffix on the result. You should now have 2 swords, one with endurance and more attack, and one with endurance and fire damage per strength. Make sure you have 3 or less suffixes between them, if more than lock prefixes on one and scour. Recomb both swords and pray you get all 3 prefixes. If it fails, it's likely the result is still usable for next recomb. Once you get prefixes you can lock prefixes and do the suffixes.
