Нужна помощь или подсказка

в Skill.java
  public static boolean isAoeBuff(final int id) {
    return (id == 1355) || (id == 1356) || (id == 1357) || (id == 1358) || (id == 1359);
  }

в SkillTable.java
    public Skill getInfo(int skillId, int level) {
        Player player = null;
        if (Skill.isAoeBuff(skillId)) {
            if (player != null) {
                skillId = skillId + player.getAoeBuffSpecific();
            }
        }
        return _skills.get(getSkillHashCode(skillId, level));
    }

    public Skill getInfo(int skillId, final Player player) {
        final int level = player.getSkillLevel(skillId);

        if (level == -1) {
            return null;
        }

        if (Skill.isAoeBuff(skillId)) {
            skillId = skillId + player.getAoeBuffSpecific();
        }

        return getInfo(skillId, level);
    }
в Player.java
    public int getAoeBuffSpecific() {
        return (int) calcStat(Stats.AOEBUFF_STRENGTH, 0, this, null);
    }
в Stats.java
    AOEBUFF_STRENGTH("aoebuffStrength", 0., 5.);
в effects Добавил EffectAurBuff.java

package l2f.gameserver.skills.effects;

import l2f.gameserver.model.Effect;
import l2f.gameserver.skills.EffectType;
import l2f.gameserver.stats.Env;


public class EffectAurBuff extends Effect {
    public EffectAurBuff(Env env, EffectTemplate template) {
        super(env, template);
    }

    @Override
    protected void onStart() {
        onActionTime();
        super.onStart();
    }

    @Override
    protected boolean onActionTime() {
            Effect efa = _effected.getEffectList().getEffectByType(EffectType.AurBuff);

            if ((efa != null) && (efa.getSkill() != getSkill())) {
                efa.exit();
            }
       
        return true;
    }
}
и в EffectType.java
    AurBuff(EffectAurBuff.class, null, false),

в Skills.xml
        <for>
            <effect name="EffectAurBuff" count="0x7fffffff">
                <add stat="aoebuffStrength" order="0x40" val="1"/>
            </effect>
        </for>
