Cannot simply ignore a summon I suppose! 
Information I learned via this thread:
The maximum action speed is 120 for tools.
With all the appropriate skills that add action speed to a specific tool you will have 40 action speed from skills.
So with a sapphire tool (30 base) you will have 70 action speed without any extra speed forged on it and 120 (speed cap) with level 10 action speed forge on it.
A mega Fast Brew will double your speed.
So equipping a diamond tool (15 Base) with all the necessary skills you will have 55 action speed before drinking a brew. With a Mega Fast Brew you will have 110. Forge level 1 busy bee on to the diamond tool and you will be at the action speed cap with a Mega Fast Brew.
