An Exarch with the Crack Shot power adds +1 to his D6 dice rolls to hit when shooting.  He may also shoot at targets at extreme range - this being defined as between normal maximum range and half as far again.  For example, a shuriken catapult has a normal maximum range of 24" and an extreme range of 24-36".  Shots at extreme range suffer the same "to hit" penalty as long range and the extra +1 to hit does not apply.              

The Exarch may leap 4" in addition to his movement during the move phase.  He may make a normal move and leap, run and leap or charge and leap but he can only leap once during the turn.   A leap will take the Exarch over any man high obstacle without penalty, including enemy models.  In addition, the Exarch can leap out of hand to hand combat at the end of any hand to hand combat phase without suffering any penalty whatsoever.                          

If the Exarch inflicts 2 or more hits then he may choose to exchange all hits for a single hit with a Strength bonus.  The bonus equals +1 for each extra hit scored, so you could exchange 2 S4 hits for a single S5 hit or 3 S4 hits for a single S6 hit and so on.

The Exarch is incredibly resilient. 
His Toughness characteristic is increased by +1.

An Exarch with the Turn Aside Blow power may parry in hand to hand combat even if he does not have a sword or another weapon suitable for parrying.  The Exarch knocks aside blows using the flats of his hands, absorbing any damage by special armored inserts.  In addition, the Exarch may force his enemy to re-roll up to two attack dice when parrying rather than just one. 

The Exarch with this skill is protected from death by fate itself.  He may re-roll any failed saving throw for his Exarch armor.  Note that this power apllies only to the Exarch's Exarch armor and not to other defences he may have.

The Eldar weaves an entrancing rune to distract his foe in hand to hand combat.  All the Exarch's foes count double the value of any fumbles.  When they roll a 1 on their attack dice this adds +2 to the Exarch's combat score rather than the usual +1.                                       

The Exarch moves with the psychic forces of nature, disguising his presence amidst the greater psychic flow.   To mortal eyes he appears shadowy and ghost-like and is very hard to hit.  Any enemy shooting at short range suffer -1 to hit penalty, while any enemy shooting at long range suffer a -2 penalty.

If an Exarch wins a hand to hand combat ( ie he has the highest combat score) then he may disarm his enemy rather than strike any hits that turn.  The Exarch causes no its, but the enemy automatically loses one weapon of the Exarch's choice.  This weapon is destroyed and can no longer be used.

An Exarch with this skill cries a fearsome War Shout as he charges.  This causes fear and the enemy must take a psychology test for fear as appropriate.

If an Exarch has this power he may increase the range of his follow-up attacks to 4"     

An Exarch with this
skill is immune to all psychology and need never take a Break test.

An Exarch with Crushing Blow skill has a +1 Strength bonus in hand to hand combat.  This bonus applies not only to the Exarch's own Strength value but also to the Strength value of any close combat weapon he is using.                                            

An Exarch with this skill receives a +1 Attack bonus.  His Attacks characteristic value is increased by +1.            

If an Exarch has Fast Shot skill then he may shoot twice in the shooting phase.  He can shoot at the same target or at two seperate targets as you wish.
