Help With Spells Exhausted

[monstruo1]

I try change spells exhausted and when i say the spell exhausted is 1 second <<<<< the same on all spells
I change exhausted on spells.xml

 <instant name="Ultimate Healing" words="exura vita" lvl="30" mana="160" aggressive="0" selftarget="1" exhaustion="600" groups="2,2000" icon="3" needlearn="0" event="script" value="healing/ultimate healing.lua">
		<vocation id="1;5"/>
