A Challenging but Entertaining Battle.
This flash was quite fun and definitely challenging. The story is quite impressive, and you have given Seelkedoom a very distinct personality, and he is not simply a flat and boring character. The voice quality was exceptional and really added to the flash. Unfortunately, I had to deduct a mark because of the numerous spelling errors. Since the flash is very dependant on the story, spelling does play a fairly significant role. Other than that though, it was truly a great flash.
For anyone struggling to defeat, Robotnik/Eggman, this is the way I defeated him: The first thing I did was cast Protect on myself. Since there is protective shelling on the robot, special attacks do not do significant damage, so just use a normal attack. When the cannon opens, attacks will do a lot more damage. Use your special attacks G. Beam and Triple Shot. You will get two free shots while the cannon charges up. After being hit by the beam you will probably need to heal. Only heal if your HP is below 2,000 because the Heal spell heals between 3,000-3,400 depending on your luck. Again, use normal attacks when he is protected by the armour.
When you run out of EP, use Purple Vortex when the cannon is charging up. That spell generally does around 1,100 damage. Again, only use the Heal spell if your HP is below 2,000. Continue to do that and you should be able to defeat him. It took me about 30 minutes to defeat him and I had to attempt it 3 times, so patience and persistence is definitely needed. Also, I strongly advise for you to look at Tails' actual stats and not at the bar, because the bar only gives an approximation of his HP, MP and EP.
