You can bait the slipstream so the party is always at 90 degree angle from you. For example, during the first add spawn, if the party is at center and you are at north, bait first slipstream so garuda will do hers westward and run through garuda. This usually means Suparna's slipstream will be eastward and you just have to run through suparna. Party members are never in the line of slipstream. During tornadoes phase, the space is a bit tighter so pull them both to the edge of the arena, bait first slipstream inward of the center, second slipstream outward of the center THEN go to pick up spiny. This allows you to pick up spiny safely without you or party eating slipstream. Of course, the OT should wait near the other side of the center tornado with spiny ready for you to provoke. If you're quick-thinking, you can adapt to it but if not, practice makes perfect. After a while, it will become natural to you.
