I came up with a new opener but a minimum of 687 Spell Speed is required as it barely leaves any room for error.
Code:
Quelling Strikes
Ley Lines
Sharpcast
0.00 240.00 B3
0.50 Swiftcast
2.01 190.00 T3 Enochian
Raging Strikes
2.01 211.68 F3
0.50 Pot
2.41 635.04 F4
2.41 635.04 F4
2.01 408.24 F1
2.01 894.60 TC Convert
2.41 635.04 F4
2.41 635.04 F4
2.41 635.04 F4
2.01 176.40 B3
2.41 294.00 B4
25.76 5590.12
PPS: 217.0078
Tried it out and it worked with 687 Spell Speed. You barely squeeze in the Fire 4 and start the Blizzard 3 at the end of Astral Fire.
